Parametric sweep results

Please login with a confirmed email address before reporting spam

Hi,

I am launching a parametric sweep over one single parameter P. For each paremeter P, I am launching a modal analysis and get two eigenmodes. Then, I integrate my solution over four subsets of boundaries and get four scalar per eigenmode: int1_mode_i,int1_mode_i,int2_mode_i,int3_mode_i,int4_mode_i with i = 1 or 2 indexes the modes.

Therefore, if P is varying from p1 to p3, I would like to store in a table:

P1 EigenValue_1_P1 int1_mode_1_P1 int2_mode_1_P1 int2_mode_1_P1 int2_mode_1_P1
P1 EigenValue_2_P1 int1_mode_2_P1 int2_mode_2_P1 int2_mode_2_P1 int2_mode_2_P1
P2 EigenValue_1_P2 int1_mode_1_P2 int2_mode_1_P2 int2_mode_1_P2 int2_mode_1_P2
P2 EigenValue_2_P2 int1_mode_2_P2 int2_mode_2_P2 int2_mode_2_P2 int2_mode_2_P2
P3 EigenValue_1_P3 int1_mode_1_P3 int2_mode_1_P3 int2_mode_1_P3 int2_mode_1_P3
P3 EigenValue_2_P3 int1_mode_2_P3 int2_mode_2_P3 int2_mode_2_P3 int2_mode_2_P3

Is there simple way to do that without using the livelink MATLAB? Maybe with accumulated probe table. I am very struggling with this basic request. Any tutorial or example will be very helpful.

For your informations, I usually end up with error messages like: "Tabe input type 'None' does not match data input type 'Eigenfrequency'. Try evaluating in another table."

Thank you all for your answers,

Best Regards,

Denis

Hi

I'm not sure what to say about how to generate such a table

But your table error comes from the fact that you try to mix a table with a single line (simple simluation input) with a table entry requiring a matrix (multiple line entry or a sweep solver sequence)

At least in 4.2a you cannot mix into the same table a derived variable from a single entrysolver sequnce (i.e. no parametric sweep) with a solution with multiple entries (several parameters).
And I do not know of a way how to mix together two tables in COMSOL, but tables can be exported to other formats/files or with cut&paste so there are manual ways around

Good luck

OK, thanks. I will do it manually then. Best Regards. Denis
