Good afternoon,
I am trying to build a model of a chamber with a flow running through it. To start, I created a 2d mesh in Gambit. I have experimental data across the inlet of the channel. I was looking to apply the timeVaryingMappedFixedValues boundary condition to the channel. I created the points file and the corresponding u, k, and epsilon files. The points file has points at the front, middle, and back of the 2d cells. I realized this was because the BC works off of a plane. When I run the simulation, I get a floating point exception error. After a lot of debugging and fiddling with the code I believe I narrowed it down to the epsilon file being the issue. If I change the boundary condition at the inlet to fixedValue the code seems to proceed just fine. What testing or changes can I make to the code to uncover the problem? I'm also open to using another boundary condition that allows me to map my data to the inlet, but I haven't found one. Thanks, Matt |
