I've made a model of a parabolic mirror and a receiver located at the focal point, to simulate radiation concentration on the receiver. i've defined these conditions:
* in "general settings", solar radiation direction along the axis of symmetry of the parabolic mirror (0,-1,0), intensity:1000W/m^2
*whitebody condition on the mirror surface and blackbody condition for the receiver.
* blackbody walls in simulation wizard window
*goal: net radiation flux, average value
*I've tried multiple result plots, non show an increased radiation intensity, of more than 1000W/m^2 on the side of the receiver that faces the mirror.
This is the first time I'm setting up a thermal or radiation analysis, so there must be something wrong with my problem definition and settings. Please help.

Thanks.
can you elaborate on what plots you're using and what value you're plotting?
also, have you done an energy balance? I noticed that your model has a very very coarse mesh. You may have asked for 1000 but you should check that you're actually getting 1000 on the face.
I would also start with everything being black bodies and then later on tune the model with other surface radiation properties like white body.
