# complex numbers in escript

Asked by
Antoine Lefebvre

I am trying to solve the Helmholtz equation for frequency domain acoustics. There is only one variable, the acoustic pressure.

This pressure is a complex quantity and the parameters of the boundary conditions are often complex numbers too.

First question: should I be able to make that work with escript?

As an example, I try to set a complex value to a boundary condition with:

bc = Scalar(0., FunctionOnBound

bc.setTaggedVal

but it seems the Scalar object does not support the complex data type...

Thanks for your help.
