Hi,
I'm trying to read in GMSH files using the API. I'm unable to figure out how to
access the mesh data from GMSH class structures.
#include <iostream>
#include <cstdio>
#include "GModel.h"
using namespace std;
int main(int argc, char **argv){
unsigned int i=0, ele=0, nodes=0;
GModel *m = new GModel();
m->readMSH("cv.msh");
/*
Is this necessary? As in, won't node numbers be always continuous? (no
missing indices)
*/
m->indexMeshVertices(true, 0, true);
nodes = m->getNumMeshVertices();
printf("No. of vertices \t%d\n", nodes);
ele = m->getNumMeshElements();
printf("No. of elements \t%d\n", ele); // this works. prints the exact
sum of all the elements
m->writeMSH("test.msh");
for(i=0; i<nodes; i++){
printf("node loop to get coordinates");
}
for(i=0; i<ele; i++){
printf("element loop to access all the elements and tag_ids");
}
delete m;
}
Many thanks
