Ashwani:

You cannot use ESSOLV without major alterations.  I do not recommend
using ESSOLV for a transient analysis or a three-field simulation.  If
you are not satisfied with the results using TRANS126, I recommend using
the ANSYS Multi-field solver.  If possible, you should upgrade to the
latest ANSYS Release (9.0 SP1).

We are doing ANSYS modelling of three physics
Electrical-Structural-Acoustics. Till now we were using TRANS126
element.
But the results are not satisfactory. We want to do it by Multifield
solver or Multiphysics capabilities. In ANSYS  manual it is written that
ESSOLVE can be used for transient analysis but in a very confusing
manner.
If somebody using ESSOLVE for transient analysis or using multifield
solver for this type of problem, I invite to interact with me.
