Experimental visualization of high order finite elements using OpenGL 4.3 compute shaders.
(WORK IN PROGRESS)
hogtess shows MFEM solutions. It also needs CMake, Qt4, and GLM:
$ sudo apt install cmake libqt4-dev libglm-dev
Configure, compile and run:
$ mkdir build; cd build
$ cmake ..
$ make
$ cd ..
$ ./build/hogtess -m data/beam.2.mesh -g data/beam.2.sln
On some Linux systems, OpenGL 4.3 may not be enabled by default. Try running with the following environment variable:
$ MESA_GL_VERSION_OVERRIDE=4.3 ./build/hogtess
