Hi, I am currently trying to solve a large PDE system with 18 PDEs and ODEs.
One of the equations is quite simple: dROS/dt = 0.06 which I implemented as follows:
`eqn_ROS = (
TransientTerm(var=RO…

I am a bit confused by distances returned when using these datas:
As input I use this simple square obj file:
v 0 100 0
v 0 0 0
v 100 0 0
v 100 100 0
f 1 2 4
f 4 2 3
And ask for distance…

I was looking at using this package, though given the size of the problems and the advective nature of the equations I would need both DG and MPI.
The table currently lists them as not working. Is …
