Hi Comsol Community,
this is my first post on this forum, any feedback on how to better explain my request is very welcome :).
I am running Comsol Multiphysics 5.4 on a remote machine via an SSH client; my workstation runs on Windows while the remote machine runs on Ubuntu 14.04.5. So far I used the GUI to create and solve my models, but now I want to run several models on the remote machine over weekends/nights via a shell script.
While attempting this I am running into the following problem:
I created a file "h-conv-std.txt" with the following content:
comsol batch -inputfile constud_maxelref_1.mph
comsol batch -inputfile constud_maxelref_2.mph
The two files constud_maxelref_1.mph and -2.mph were already created and are located in the same folder as the .txt script file on the remote machine. Now I try to run the script via the command line of the SSH client, calling
bash h-conv-std.txt
Comsol Multiphysics starts, but can't find the files, this is the output I see in the console:
userXXX@SVXXXX:~/190502_Comsol_Models/190719_convergence_studies/190719_h-convergence$ bash "/home/userXXX/190502_Comsol_Models/190719_convergence_studies/190719_h-convergence/h-conv-std.txt"

The funny thing is: when I start the comsol batch directly (instead of using the script), it works - see following output:

Any suggestions what could cause this behaviour? Maybe someone at least knows some tricks to narrow down if the issue is with Comsol Multiphysics or maybe with my rudimentary knowledge of how Ubuntu/Linux works?
Thanks in advance for your feedback!
Kind regards,
Sebastian
