Hi, everyone!

when I turn on the solar ray tracing model and initialize my model, there will be a message saying: 'Node 999999: Process 15040: Received signal SIGSEGV', and fluent will close by itself automatically.

Meanwhile, I found a cortexerror.log file, which says:
Error [cortex] [time 5/23/21 2:6:5] Cortex received a fatal signal (SEGMENTATION VIOLATION).

My model runs OK when I turn off the solar ray tracing model...

Could anyone help? Thank you so much in advance!

I do not have any UDFs.

In addition to the post, I found that the problem is in the boundary condition.

I was trying to model a double pane thermotropic glazing (the absorptivity and transmitivity of each layer of glass vary with temperature). I set the front and back glass as 'thin wall', and in the boundary condition - radiation - solar boundary condition, I try to vary the absorptivity and transmitivity using 'expression'. The expression is as follows:

IF(StaticTemperature<301.15[K],0.26,0.37)

And the problem occurs....I also tried IF(Temperaturewall<301.15[K],0.26,0.37) and IF(Temperaturewall(thin)<301.15[K],0.26,0.37)

I found that If the absorptivity and transmitivity are constant, the model runs perfectly.

Could anyone help please? Thank you so much!!!
