Hello,
I must have done an error but when I start my calculation, no file type 0001.rad is written. Do you know how to solve this ? Is it possible to restart a calculation (to simulate more time) without this file ?
Thank you,
Regards
Guillaume
Hi Guillaume,
In order to restart a run you should have a second engine file.
Ensure that while exporting model file Auto export engine file option is checked
<?xml version="1.0" encoding="UTF-8"?>
Hi,
Thank you for your reply !
The 'auto export engine file' was checked, but I may have also checked 'Merge starter and engine file', is that the reason why I do not have any 0001.rad ?
Is it still possible to rerun my calculation ? Or do I have to start it again from the beginning ?
Thanks a lot for your help,
Regards,
Since you have checked 'Merge starter and engine file' option, the engine control cards defined will be in the starter file (_0000.rad) itself and that's why engine file was not created separately. Open the _0000.rad file in Textpad or Notepad and ensure that engine control cards are present.
If the control cards are present in the starter file you can run the same.
Do I have to rename it like I would have if I had the 0001.rad ? Do I have something to do before clicking 'Run' ?
I mean, if I juste run the 0000.rad again, it will erase my calculation and do it again, won't it ?
Finally, how do I set the time I want to rerun the calulation for ?
Sorry for all these questions but I am a beginner and I didn't find these answers on the documentation I have about Radioss.
There is no need to rename, since both the starter and engine files are merged. You can directly run the file.
To provide the run time, either open the _0000.rad file Textpad or Notepad and manually change the run time under /RUN. Please see the attached image.
Else import the file in HyperMesh, change the run time and export again.
Since you are a beginner I recommend you to practice a crash box tutorial which is available at https://altairuniversity.com/wp-content/uploads/2016/11/Crash_Box_1.pdf
Also, you can get exposed to various analyses using Altair tools at https://altairuniversity.com/conceptual-design-of-a-3-wheeler-motorbike/
Thanks a lot !
