If you don't care about specifics, from the build directory run
$ cmake ..
$ make
$ make installThis generates a veritas executable in the bin directory and sets up the environment ready to start running straight away.

abstract = {The dynamics of collisionless plasmas can be modelled by the Vlasov-Maxwell system of equations. An Eulerian approach is needed to accurately describe processes that are governed by high energy tails in the distribution function, but is of limited efficiency for high dimensional problems. The use of an adaptive mesh can reduce the scaling of the computational cost with the dimension of the problem. Here, we present a relativistic Eulerian Vlasov-Maxwell solver with block-structured adaptive mesh refinement in one spatial and one momentum dimension. The discretization of the Vlasov equation is based on a high-order finite volume method. A flux corrected transport algorithm is applied to limit spurious oscillations and ensure the physical character of the distribution function. We demonstrate a speed-up by a factor of 7 {\texttimes} in a typical scenario involving laser pulse interaction with an underdense plasma due to the use of an adaptive mesh.},
