1-D 1-FLUID SOL MODELING WITH FINITE-ELEMENTS

We present here the numerical solution of a 1‐D (along the magnetic field) 1‐Fluid time dependent set of SOL model equations (particle, momentum and energy balances) by means of finite element (FE) discretization of the space coordinate. The results are compared with those of the SOLID finite difference (FD) code [W. Schneider, et al., J. Nucl. Mater. 121, 178 (1984)] and good agreement is found between the two. This shows the potential of the FE to work also in the presence of strong convection, as is the case near the divertor plate or limiter ‐ a feature which if confirmed in the 2‐D case will make them particularly attractive for SOL simulation.
