We present a new software that aims to calculate the effective space charge distribution of a silicon detector. The software uses TRACS (TRAnsient Current Simulator) to simulate the induced transients currents in a detector under edge-TCT illumination. Inside TRACS a Neff(z) profile is assumed. The parameters of the profile are extracted from a fit of measured transient currents to the simulation. Since this is a CPU demanding process, TRACS was parallelized and is ran in a multicore machine. This new TRACS version with fitting capabilities are available in the CERN-cloud service.
