Hi,

I'm using COMSOL 4.2a to simulate electric fields on a cell in a micro-channel. I use the LiveLink for MatLab to move around the cell in the channel and recalculate the electric fields in the new positions (a new mesh is created for each new position).
In order to evaluate the electric field at the same points on the cell surface for each iteration, I need the mesh points to remain constant on the cell surface. I tried to use the 'Distribution' command on the cell edges, i.e.:
model.mesh.create('mesh1', 'geom1');
model.mesh('mesh1').feature.create('ftet1', 'FreeTet');
model.mesh('mesh1').feature('ftet1').feature.create('size1', 'Size');
model.mesh('mesh1').feature('ftet1').feature('size1').set('hmax', '4E-6');
model.mesh('mesh1').feature('ftet1').feature('size1').set('hmin', '4E-8');
model.mesh('mesh1').feature('ftet1').feature.create('dis1', 'Distribution');
model.mesh('mesh1').feature('ftet1').feature('dis1').selection.set([index_edges_cell]);
model.mesh('mesh1').feature('ftet1').feature('dis1').set('numelem', '40');
model.mesh('mesh1').run;

Yet, the points don't remain constant. My question is whether there is a way to copy the mesh on the cell surface alone to the new iteration of the model and then complete the remainder of the geometry meshing? Perhaps the 'Reference' command can be helpful (I didn't understand how to apply it usefully...).

Thanks for your help!
