I'm receiving an error (not specified) when restarting a 3D simulation which has the ReynoldsStresses filter activated. I don't get the error when the simulation is 2D nor when I use the AverageFields filter. So it just happens when I use the ReynoldsStresses filter in the Quasi-3D simulation. I'm also solving a scalar equation. Would it be a bug in this specific setup condition? I tried versions 5.4 and 5.5. Or does anyone know a workaround? I'm doing separated averages to combine later with the respective FieldConvert module for now. Thank you very much, Daniel.
