mumax-view is a web app to visualize OVF files.
mumax-view is meant to be compiled to web assembly using the emscripten compiler toolchain.
If you have to emscripten compiler toolchain installed, then you can build mumax-view as follows
git clone --recursice https://github.com/JeroenMulkers/mumax-view
mkdir -p build && cd build
emcmake cmake ..
emmake make
Alternatively, you can build mumax-view using the emscripten/emsdk docker image with the following one liner:
docker run --rm -v $(pwd):/src -u $(id -u):$(id -g) emscripten/emsdk \
sh -c "mkdir -p build && cd build && emcmake cmake .. && emmake make"
