I used to build ISPC on MinGW64 (without ispc-runtime lib) which worked fine. Now after upgrading from ispc version 13 to 18 I get the following error when linking against...

Velocity may not be extrapolated sufficiently far to accomodate CFL number

Hi, browsing through the source code, I came across the following possible glitch: Calculating the number of "extrapolation layers" (i.e. L1-distance) this way may significantly underestimate the actual number of...

Equation 3.18 takes the *relative* fluid-collider velocity for boundary projection. This does not seem correct. Consider the simple case of of verctical wall (normal_collider=(1,0) uv_collider = (0,1) and uv_liquid_boundary=(0,0). Relative...

double factor = scale*_v->volume(x, y + 1)/_vDensity[_u->idx(x, y + 1)]; should be replaced with double factor = scale*_v->volume(x, y + 1)/_vDensity[_v->idx(x, y + 1)];

setBoundaryCondition() simply sets the velocity of SOLID cells to the velocity of the solid body. However, this does not enforce the correct boundary condition which is: dotprod(velocity,solid_boundary_normal)=0. Solution: setBoundaryCondition() should...
