Can it be possible to import FORTRAN script in initial values? Instead of sine wave as initial condition we want to use random initial wave condition. The random wave initial condition is in FORTRAN language script. Otherwise can we run it as MATLAB code and import it to initial value condition?

Hello,

It seems possible using the "External" function feature in "Global definition">"Function">"External". Note that this feature works for C language but you could use wrapper function for example.

Also, you can use a MATLAB function in "Global definition">"Function">"MATLAB" (you need the LiveLink for MATLAB).

For more help, please contact COMSOL technical support.

Note that you can define random function in COMSOL Multiphysics "Definitions">"Function">"Random".

I hope this helps.

Regards,

Mickaël
