Hi there,

i'm actually testing your cfd tool for matlab for fluid simulation of air for simulations for my phd.

I'm using the Version 1.5. After reviewing the tutorial from: https://www.featool.com/doc/index.html im a little confused, that in my version after starting the tool and selecting 2D, there is no possibility to select the navier-stokes-equation. What's the reason for that.

Afterwards im trying to simulate a structure with a compressible fluid but get the error message "Warning: Matrix is singular to working precision". Where does this error come from?

Thanks in advance for your help.

Best,
Valentin
