Hi guys,

does anyone know if in 4.2 there are the equivalent commands of "postplot" and "postinterp" of version 3.5a for accessing data, for example, of a particle tracing in Comsol w/ Matlab?
I may have found a workaround to the apparent lack of these commands, but if anyone know they are there, please tell me... I'm going nuts...

Best
J

Hello Jacopo,

the postplot and postinterp functions were renamed to agree with the new name convention to mphplot and mphinterp, respectively.

You can find more info about these two in two doc-PDF files in 'MATLAB livelink' folder.

BTW: I'm still wondering if you made to manage the data extraction in MATLAB for COMSOL 4.2. Is it possible to get any particular particle data? And can we set some 'individual' particle attributes, for example just like in Ansys Fluent?

I have tried to put the results into a variable using

h=mphplot(model,'pg1')

where "model" is the model name and "pg1" is the result node. However, the data structure is too big to be saved in the variable "h".

I have tried to extract data by "mpheval" but I cannot get the proper name of the data structure for particle data (ptr1?).

I got stuck. I would appreciate any help from you.

Thank you.

Kind regards,
Peter
