disable diffusion matrix

Question

I would like to use openCARP to solve many ODE at the same time with different parameter values at each node. However, I noticed that the flag -diffusionOn 0 (that was present in carpentry) to toggle diffusion on/off no longer works here.
Are there workarounds?

Thanks,

Cesare

There is no way of skipping the linear solver in openCARP. If this is important for you, we are of course happy to receive merge requests implementing this feature.

This part of the code should be a good starting point: https://git.opencarp.org/openCARP/openCARP/-/blob/master/physics/electrics.cc#L302

We collected some hopefully helpful info and guidance on code contributions here: https://opencarp.org/community/contribute
