hello my friends.
My name is Navid Samiei and I am a master student. In my dissertation, I work on advection and diffusion of air pollutants with LBM and due to the difficulty of parallelism, I decided to use PALABOS for this purpose but I encounter some problem in this library. First of which is the implementing of STL file in this program for which I receive this error message.
here my code for this program:
pcout << std::endl << “Processing the object geometry.” << std::endl;
Array<T,3> center(cx, cy, cz);
Array<T,3> centerLB(center);
TriangleSet triangleSet (“stack.stl”, DBL);
this is the error message:
example: /home/navid/Desktop/example/…/palabos-master/src/offLattice/triangleSet.hh:237: void plb::TriangleSet::readSTL(std::__cxx11::string, plb::TriangleSelector*) [with T = double; std::__cxx11::string = std::__cxx11::basic_string]: Assertion `fp != 0’ failed.
Processing the object geometry.
