Dear all,
I built a cardiac cell model in 3D. There are two domains as the extracellular and intracellular space. Two Laplace's equations are applied to these two domains (∇∙8∇V_i=0,∇∙8∇V_e=0). Then I used 'boundary ODEs and DAEs' to apply two boundary conditions to interface between the extracellular and intracellular space (membrane) (8∇V_i=(d(V_i-V_e))/dt+I_ion,8∇V_e=-d(V_i-V_e))/dt-I_ion). When I ran it, it pops up a error like 'Failed to find a solution. Segregated Step 1 Singular matrix'. I think it is probable because the potential distribution is discontinuous over the membrane. How can I solve this problem?
Best wishes
