Comsol Data Export and Automated Equation Running Tips

[smh204]

Hi

i'm solving a system of 6 ODE's (time dependant) and wish to export them to a set or 1 of ascii files that can be imported to origin (the format being the variable against the time) . is there a way to do this? also is there a way to run a set of eqns changing the some constants each time and exporting the data automatically.

any help would be massively apprecated!

Export -> Export Post Processing data exports to ascii. How familiar are you with the scripting facilities of Comsol? It enables you to script your models and all aspects of them, post-processing included.

Hi there, it is possible to export data from Comsol to ASCII files by using the "Export Data" feature. You can select the variables you want to export and choose the format for the data. This should allow you to import the data into Origin as desired.

As for running a set of equations with changing constants and exporting the data automatically, this can be achieved by using the built-in parameter sweep feature in Comsol. You can specify the constants you want to vary and the range of values for each one. Comsol will then automatically run the equations for each combination of values and export the data for each run.

I hope this helps and please let me know if you have any further questions or need clarification. Happy modeling!
