is inhomogenously filled meshcells

hello every body ,
plz help me.
when i simulated antenna in layered bio media then there are some error produced in cst software which are as follows?
"Memory resources exhusted...solver stopped to solve matrix...program aborted"
please tell me how can i remove this error?
one more error:
" the port 1 is inhomogenously filled within the first three mesh cells. cannot start solver"
plz tell me its solution...
 

Hi,
error with mesh cells:
can you show me detail your port ? you must probably change design or increase mesh density.....
 

for this analysis i use simple three layer human body model (skin,fat and muscle) and when i try to simulate then i get this error" the port 1 is inhomogenously filled within the first three mesh cells. cannot start solver" and for this problem i increased the mesh cells and then this problem is remove but the new problem is come in to picture "Memory resources exhusted...solver stopped to solve matrix...program aborted"
 

And how many meshcells have you ? I think, that you have problem with memory in PC, what is your RAM ?
 

no. of mesh cell are around 7 crore and my system have 2.25GB RAM.

sorry, i do not know what do think, if you say "7 crore"

and can you send your CST file ? ( just send model/3D/ model.mod (yellow arrow) and model.par)
 

in order to give a matched port and evaluate the mode at the port, CST needs that the waveguide extent inside the calculation domain for three or four mesh cell.

You can do two thing, increse mesh cell (not the best) or extend the waveguide section without curves or angle for 0.25lambda.
