Seem to be getting an odd error on line 6 of Sim.cpp

Any solutions?

Hello.

First; I want to congratulate you for your contribution. It is great!!

Second; I am considering a project where I want to simulate volcanic lava running down the slope of a mountain (in 2D).

I don't know if it is possible to do it with this approach. The first question I have is whether it is possible to simulate the effect of the lava going around obstacles it may encounter on its way, such as houses (rectangles). Do you have an opinion on how to implement this?

In other words, I wonder how this "fluid" will work interacting with rigid objects/bodies. I guess, as it is not a particle system per se there are no collisions to detect. :-D

Thanks!
