Mesh Problem?

Hi, guys.
I got some problem with this message after computation.
'Failed to find a solution.
Singular matrix.
For mesh-case 0 there are 1 void equations (empty rows in matrix) for the variable mod1.mef.mi1.term1.V0_ode.
at coordinates: (0,0,0), ...
and similarly for the degrees of freedom (empty columns in matrix).
Returned solution is not converged.'
I think it is mesh problem but I do not know how to fix it.
I need your guys help!!!!
P.S I cannot attach my file because it is too large. Sorry.

Hi
I do not believe its a mesh issue, if you mesh node& statistics are OK and it does not say "elements not meshed" it's rather that you ODE expression is missing a boundary condition or some decent initial values.
To make a model smaller, so you might upload it, just do a Edit clear all mesh, Edit clear all solution and File reset model, then save as with a new name and upload ;)

Good luck
