Question

Hello,

 

I am working on my bachelorthesis right now. At my university we use "LMS VirtualLab", which works fine with the Altair PUNCH-File format. In order to get my final results I need to imitate the .pch-file format after doing a fft in Matlab on my results (which were calculated by RecurDyn). I achieved to get a file format that looks exactly the same as the one that can be written from HyperWorks. Still it does only work with LMS VirtualLab if I open it in "Notepad++" and save it with a different name, without changing anything else. I defined it already to be UTF-8, but it did not solve my Problem. Can anybody tell me what I fail to see? Both files are attached: punch.pch is the file which is not working, punch2.pch is the working one.

 

 

Kind regards

 

Konstantin Heiss

You are speaking about "Nastran", "LMS VirtualLab", "RecurDyn",... so my question is "What's related to Hyperworks?"

Hyperworks can export a working file format. Thats why I asked here. I wanted to know if somebody knows, what the difference between my files and the format exported from Hyperworks, cause I can't find any.
