<div dir="ltr">Hello, <br>I am trying to run a 3T, MGD simulation with PROPACEOS files for the EoS. The simulation runs well when the target material is set at a high temperature in the .par file. However, at around 5000 K and below, the target materials (Cu and CH) behave erratically. As in the electron temperature of the material will jump up to around 5000K in the first time step. The simulation outputs this error:<div>[RadTrans] ***** ERROR DETECTED IN Diffuse_solveScalar ***** <br>-1 1 3
