Every user-supplied value in the file, numbers or text, to become a parameter. One of the key breakthroughs that ANSYS introduced in the late 80’s was converting their input file from a formatted text file that simply specified the model being solved with a simple text command language that could also define the model fully. Small, fast, and a great way to experiment with new fet What is APDL and why do we need it?ĪPDL stands for ANSYS Parametric Design Language. Two beams held at their base that are loaded in various ways. It is what we call a “Towers of Test” model. But all of those capabilities are still there and accessible to the user.īefore we go further, let’s talk about the simple model we will be using for this post. However, the user interface, and especially the embedded geometry tool, could not keep up and much of the pre- and post-processing was replaced by ANSYS Mechanical. Swanson.) Over the following decades, the program grew to become a fully featured FEA program that could do almost anything. (if you want to learn more about the history of ANSYS, please check out our interview with Dr. This is the original ANSYS product that Johns Swanson wrote in the early 70’s. The key thing to remember is that when you click Solve in ANSYS Mechanical, it generates an input file that is then read into ANSYS Mechanical APDL in batch mode. 
If you have never used ANSYS Mechanical APDL a lot of what we are going to talk about may sound like another language. There is a lot to cover, so get comfortable. That is why we decided to update that seminar as a blog article, making it more searchable while we bring it up to date. But again and again our tech support people find that users push the envelope with their tools and to do what they need to do, they need to get inside the solver tool using the APDL scripting language. ANSYS Mechanical has grown and scores of features have been added, removing the need for a lot of the functions and features that people needed APDL scripts for. You can have your cake and eat it too.Ī lot has changed since we did our last seminar on this topic, back in May of 2011. But it also allows users to access the power of the underlying solver through the native language it uses, APDL.
This modern and ever-improving interface allows users to create, run, and post-process models with power and ease. One of the most powerful features in ANSYS Mechanical is the fact that it leverages the ANSYS Mechanical APDL solver.
