I am trying to use coefficient from PDE to solve helmholtz type partial differential equation.
(I know there is helmholtz equation, but both module doesn't working)
So, first I am using COMSOL 4.4 with MATLAB, and I follow the instruction as following link to use MATLAB function as source. (www.comsol.kr/support/knowledgebase/1093/)
since the input matrix is 20x60, I discretized my geometry into 1200 elements,
The problem is after i meshed my geometry, COMSOL continuously says as following
The following feature has encountered problem:
Incorrect size of returned vector, 2000 elements were expected, but the returned matrix was 20x60
- Function: f
- Feature: Stationary Solver 1 (sol1/s1)
So, I have tried 20x100 matrix, then COMSOL says
The following feature has encountered problem:
Incorrect size of returned vector, 400 elements were expected, but the returned matrix was 20x100
- Function: f
- Feature: Stationary Solver 1 (sol1/s1)
any help or comments will be appreciated
