How to use derivative and divergence functions:

Nov-30-13 11:27:32

I am new with openmodelica. I want to use partial differential equations for modeling inter-atomic attractions. I don't know how to implement PDEs, derivatives and divergence in openmodelica. I need help plz.

Hello Yahya

As far as I know Modelica does not include a standard way to implement PDEs.

However if your geometry is not complex you can assemble the equation system of the discretisation easily by hand.

There is an excellent example in the book "INTRODUCTION TO PHYSICAL MODELING WITH MODELICA" by Michael Tiller, page 120.

Best regards
Koldo
