Solutions to mumax3: command not found

How To Fix mumax3: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu mumax3 is provided by mumax3 package.

mumax3 is:

mumax3 is a GPU-accelerated micromagnetic simulation program developed at the DyNaMat group of Prof. Van Waeyenberge at Ghent University.

A speed-up of the order of 100x compared to CPU-based simulations can easily be reached, even with relatively inexpensive gaming GPUs. Additionally, the software is optimized for low memory use and can handle about 16 million FD cells with 2GB of GPU RAM.

Features:

Landau-Lifshitz micromagnetic formalism
Magnetostatic field
Heisenberg exchange
Arbitrary inter-region exchange like RKKY coupling
Dzyaloshinskii-Moriya interaction
Spin-transfer torque (Zhang-Li and Slonczewski)
Uniaxial and cubic magnetocrystalline anisotropy
Thermal fluctuations (Brown)
Voronoi tessellation
Time- and space dependent material parameters
Arbitrary complex excitation (field, current)
Simulation window can automatically follow a moving domain wall
Edge charges can be removed to simulate an infinitely long geometry
Optional 1D, 2D or 3D periodic boundary conditions

To fix this problem, we can install more using the command below.

sudo apt-get -y install mumax3

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install mumax3.

sudo apt -y install mumax3

Or if you have aptitude installed you can use the following command.

sudo aptitude install mumax3
