stiff solver ,, coupling ..
 

Hello everyone,

I am trying to solve a set of stiff odes. I tried flcvode.h but couldn't succed, so now I am trying to use an external solver from within my UDF. It's that I want to call SCILAB at the end of each time step and read back in the results. Does anyone have any idea on how to execute an externel software from UDFs ?

Any suggestions will help.

Thank you in advance.
