Hi friends,

I have a problem that "1.#QNAN" is displayed instead of values in reference values and initialization step and then the initialization will diverge!

The error occurs even after mesh reading.

Is there any idea about this problem?

Please see the attached image.

Please help me if you can.

2D, axisymmetric, Double precision, Version 17.0

I find the problem.

When I change the "Axisymmetric" to "Planar", the error disappears and the values appear in reference values and initialization, but the simulation is Axisymmetric and I should solve it in Axisymmetric mode.

Is there any idea or conditions for Axisymmetric problems?

Really there is no idea?!!!

this simulation is so necessary for me.

do you properly set up your b.c and material property?

maybe there is unrealistic value or something similar

It solved.

The Axisymmetric mode in Only about x-coordinate.
The case was around y-coordinate. I fixed it and the error solved.
Thank u 4 your response.
