DEIDynamic nsteps #(in)
dumpcoef #(rn)
[deltaT #(rn)]

Represent the linear explicit integration scheme for dynamic problem solution. The central difference method with diagonal mass matrix is used, damping matrix is assumed to be proportional to mass matrix, $ \boldsymbol{C}
= \mathrm{dumpcoef} * \boldsymbol{M}$, where $ \boldsymbol{M}$ is diagonal mass matrix. deltaT is time step length used for integration, which may be reduced by program in order to satisfy solution stability conditions. Parameter nsteps specifies how many time steps will be analyzed.
