how to change material properties of a mesh element in a loop

Hi

I am working with livelink to maltab and I have a geometry with three domains assigned with certain material properties. After solving my model for the first iteration, I take the results for each node or element and depenting on the values I get I need to change the material properties of that node or element.

I think that I can't use somehow the command
model.material('<mat tag>').selection.set([<point>]) e.g. for each point node, since the materials are assigned to domains, geometries or boundaries, right?

Do you have any idea about how to make it? For each iteration maybe I have to re-create the geometry including a new domain (even if this is an element) and then assign the domain with the new material properties? how can I create a new domain from matlab?

Thanks

Hi Maria,

have you found any solution to your problem yet? I have been looking for ages how to do the same thing as you described!

Have either of you found a solution? I am trying to change the property values for each individual element. I am currently able to create an interpolation function based on element values and the property I want to assign to individual mesh elements (in my case hydraulic conductivity). This code runs, but the assigned hydraulic conductivities are assigned to different elements than the model I input to the interpolation function.
...

Some sample code:
"model.file.create('res2');
model.func.create('int1', 'Interpolation');
model.func('int1').set('importedname','test_hyd_cond_elems.csv');
model.func('int1').set('modelres', 'res2');
model.func('int1').set('importedstruct', 'Spreadsheet');
model.func('int1').set('importeddim', '1D');
model.func('int1').set('sourcetype', 'model');
model.file('res2').resource('test_hyd_cond_elems.csv');
...
expre = 'int1(meshelement)';
model.physics('dl').feature('smm2').set('K', {expre; '0'; '0'; '0'; expre; '0'; '0'; '0'; expre});"

Thank you in advanced for you help,
