meep command not found

In this troubleshooting guide we learn how to fix meep command not found error message

Introduction

When you run more command in linux terminal / console, you get the following error message

meep: command not found

or when using sudo you get the following error message

sudo: meep: command not found

In Ubuntu meep is provided by meep-openmpi package.

meep-openmpi is:

Meep is a free and open-source software package for electromagnetics simulation via the finite-difference time-domain (FDTD) method.

Its features include:

Free and open-source software under the GNU GPL.
Complete scriptability via Python, Scheme, or C++ APIs.
Simulation in 1d, 2d, 3d, and cylindrical coordinates.
Distributed memory parallelism on any system supporting MPI.
Arbitrary anisotropic electric permittivity ε and magnetic permeability μ, along with dispersive ε(ω) and μ(ω) including loss/gain, nonlinear (Kerr & Pockels) dielectric and magnetic materials, electric/magnetic conductivities σ, and saturable gain/absorption.
Perfectly-matched layer (PML) absorbing boundaries as well as Bloch-periodic and perfect-conductor boundary conditions.
Exploitation of symmetries to reduce the computation size, including even/odd mirror planes and 90°/180° rotations.
Arbitrary current sources including a guided-mode launcher.
Frequency-domain solver for finding the response to a continuous-wave (CW) source.
ε/μ and field import/export in the HDF5 data format.
GDSII file import for planar geometries.
Materials library containing predefined broadband, complex refractive indices.
Field analyses including Poynting flux, mode decomposition, near to far transformations, frequency extraction, local density of states (LDOS), modal volume, Maxwell stress tensor, arbitrary functions; completely programmable.

This package contains the MPI version of the software. As opposed to meep-mpi this package also contains the OpenMPI version of libhdf5.

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

sudo apt-get -y install meep-openmpi

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

You can also use apt command to install meep-openmpi.

sudo apt -y install meep-openmpi

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

sudo aptitude install meep-openmpi

In this tutorial we learn how to fix meep command not found error in Ubuntu / Debian / Kali Linux or Raspbian distribution.
