This part of the philosophy also applies to how we design and build PADT\u2019s internal structure, tools we use, and processes we adopt.<\/p>\n<p>Among the growing pains of most engineering and simulation organizations is the constant growing demand for storage capacity, data management, and protection, and BOATLOADS of computing power. Sadly, PADT engineers have yet to develop a near infinite storage capacity (like <a href=\"http:\/\/www.sciencemag.org\/news\/2017\/03\/dna-could-store-all-worlds-data-one-room\" target=\"_blank\" rel=\"noopener\">DNA for storage<\/a>) or a working <a href=\"https:\/\/en.wikipedia.org\/wiki\/Quantum_computing\" target=\"_blank\" rel=\"noopener\">quantum computer<\/a> that can run ANSYS. So we\u2019re in the same boat with everyone else. We have been exploring what are our major pains and what optimizations can be made to our simulation environment (about 2,000 cores of Cube Simulation Cluster Appliances) as well as a structured, controlled solution for engineering data management.<\/p>\n<p>As always we started by looking inwards:<\/p>\n<ul>\n<li>What skills are available, or learnable within PADT that can help address the need?<\/li>\n<li>\u00a0What tools &amp; resources do we have access to?<\/li>\n<li>What do we need to acquire or buy?<\/li>\n<\/ul>\n<p>The immediate and most obvious answer was to utilize PADT\u2019s internal pool of knowledge and an ANSYS product called Engineering Knowledge Manager (EKM for short).<\/p>\n<p>ANSYS EKM is a tool purposely developed to provide a turnkey solution for simulation process and simulation data management. This means that users can \u2013 through a single interface \u2013 perform a full simulation lifecycle. In the next few paragraphs, I will briefly go over some of the main features of ANSYS EKM with a couple of screenshots for good measure.<\/p>\n<figure id=\"attachment_10907\" aria-describedby=\"caption-attachment-10907\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f01.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f01.png\" height=\"317\" width=\"550\" class=\"wp-image-10907 size-large sp-no-webp\" alt=\"\" fetchpriority=\"high\" decoding=\"async\"  > <\/picture><figcaption id=\"caption-attachment-10907\" class=\"wp-caption-text\">Figure 1. ANSYS EKM Architecture<\/figcaption><\/figure>\n<h2>Interactive and batch submission to high-performance computing resources<\/h2>\n<p>For PADT, a very practical feature of EKM is the ability to easily interface to existing High-Performance Computing (HPC) infrastructure. By communicating through ANSYS Remote Solve Manager (RSM), EKM is able to effortlessly interface to most HPC schedulers and resource managers for both the Windows and Linux worlds.<\/p>\n<p>This feature is huge because analysts can seamlessly upload their models into the secure EKM repository, submit the jobs to the HPC cluster\/s, monitor their runs, and upload their choice of results directly into EKM for review and post-processing.<\/p>\n<p>EKM works hard to keep the interface familiar to flatten the learning curve and keep things simple by making the batch submission menus as close as possible to the local ones.<\/p>\n<figure id=\"attachment_10908\" aria-describedby=\"caption-attachment-10908\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f02.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f02.png\" height=\"432\" width=\"550\" class=\"wp-image-10908 size-large sp-no-webp\" alt=\"\" decoding=\"async\"  > <\/picture><figcaption id=\"caption-attachment-10908\" class=\"wp-caption-text\">Figure 2. Simplicity of Batch Jobs<\/figcaption><\/figure>\n<p>At PADT, whenever we are debugging models or application behavior, we want to have an interactive session to have the most control and visibility of the environment. With EKM, we can utilize the remote visualization &amp; acceleration tool Nice \u2013 DCV. DCV is launched from within EKM and provides access to an interactive desktop on a cluster target while also accelerating OpenGL graphics for visually intensive programs.<\/p>\n<figure id=\"attachment_10909\" aria-describedby=\"caption-attachment-10909\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f03.png\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f03.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f03.png\" height=\"335\" width=\"550\" class=\"size-large wp-image-10909 sp-no-webp\" alt=\"\" decoding=\"async\"  > <\/picture><\/a><figcaption id=\"caption-attachment-10909\" class=\"wp-caption-text\">Figure 3.

Features like highly granular access control, file and folder sharing and collaboration, version control, check-out and check-in procedures, and many more are enabled and very powerful out of the box. Other more advanced features such as data aging, auto-archiving, auto unpacking option for zip files are also very useful.<\/p>\n<figure id=\"attachment_10910\" aria-describedby=\"caption-attachment-10910\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f04.png\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f04.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f04.png\" height=\"273\" width=\"550\" class=\"size-large wp-image-10910 sp-no-webp\" alt=\"\" loading=\"lazy\" decoding=\"async\"  > <\/picture><\/a><figcaption id=\"caption-attachment-10910\" class=\"wp-caption-text\">Figure 4. Data Management Interface<\/figcaption><\/figure>\n<p>The capabilities don\u2019t end here as EKM integrates directly with ANSYS Workbench. Analysts can seamlessly access their EKM repository from Workbench to perform any modifications and directly save back to EKM without the need to switch applications. Check-outs are automatically checked back in and new version numbers can be created automatically as well.<\/p>\n<h2>Metadata extraction<\/h2>\n<p>An extremely powerful piece of EKM is the metadata extraction engine that is baked into the core. EKM stores files as two entries, original file, and file metadata. EKM goes beyond the basic filename, date, owner metadata and digs deeper. It digs into the CAE meaningful metadata of the model, setup, material properties, element counts, mesh type and so on. It also extracts snapshots of the geometry, contours and in some cases even provides a 3d model that can be directly manipulated by the user. A sample of an ANSYS Fluent case metadata is below.<\/p>\n<figure id=\"attachment_10911\" aria-describedby=\"caption-attachment-10911\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f05.png\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f05.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f05.png\" height=\"440\" width=\"550\" class=\"size-large wp-image-10911 sp-no-webp\" alt=\"\" loading=\"lazy\" decoding=\"async\"  > <\/picture><\/a><figcaption id=\"caption-attachment-10911\" class=\"wp-caption-text\">Figure 5.

Metadata Includes Interactive 3D Models<\/figcaption><\/figure>\n<p>Metadata extraction is supported for ANSYS data types and the ability to define new data types is straightforward and easy to do for any other CAE data types or in-house codes.<\/p>\n<h2>A rich search capability that goes beyond filename, owner and timestamps.<\/h2>\n<p>How many times have I kicked myself for not using meaningful file names with versions and useful time stamps and ended up spending hours opening a file for a quick peek to find that it isn\u2019t the file I am looking for? Too many.<br \/>\nCAE models have hundreds of variables and parameters that are embedded in them. Wouldn\u2019t it be useful if someone came up with a system to store CAE models where an analyst can simply type a search variable and it would search not only name and timestamps but actually dig into the guts of the model and search those? Well EKM is one such system. Analysts can search using thousands of field combinations that encompass everything from material properties to partitioning methods, boundary conditions to cell counts, you get the idea, it&#8217;s pretty awesome!<\/p>\n<figure id=\"attachment_10913\" aria-describedby=\"caption-attachment-10913\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f07.png\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f07.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f07.png\" height=\"458\" width=\"550\" class=\"size-large wp-image-10913 sp-no-webp\" alt=\"\" loading=\"lazy\" decoding=\"async\"  > <\/picture><\/a><figcaption id=\"caption-attachment-10913\" class=\"wp-caption-text\">Figure 7.

As we will see later, batch submission is baked right into the EKM capabilities and workflows can automatically launch batch submission scripts to a cluster and get the simulation going as soon as the proper files are loaded and that stage in the process is released.<\/p>\n<figure id=\"attachment_10914\" aria-describedby=\"caption-attachment-10914\" style=\"width: 550px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f08.png\"><picture><source srcset=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f08.webp \"  type=\"image\/webp\"><img src=\"https:\/\/www.padtinc.com\/wp-content\/uploads\/2022\/02\/padt-ansys-ekm-f08.png\" height=\"147\" width=\"550\" class=\"size-large wp-image-10914 sp-no-webp\" alt=\"\" loading=\"lazy\" decoding=\"async\"  > <\/picture><\/a><figcaption id=\"caption-attachment-10914\" class=\"wp-caption-text\">Figure 8.
