Unknown Error for Panels

[TSOFA]

Hi,

I have a RC structure that at the basement there are 2 electrical channels which I modeled as panels/shells. When I run the module 'slab required reinforcement', for two of my panels (142&143) there is a message ' unknown error for panel 142(&143), Incomplete results for panel 142(&143)'. I checked the table plate and shell reinforcement and there are errors only for the case of 142 panel at two out of 210 nodes of the panel. For panel 143 there isn't any error message at the table. The program gives me maps with reinforcement results. How I can correct the error and if I can't, is it safe to use the results? the error is only at two nodes. Unfortunately my file is too large ( I can't understand why, I erased results and FE) so I can't send it

If there are no values calculated in a single point or few locations you may assume values similar to the neighbouring ones instead. For your models I would run calculation with the global averaging of forces switched off as this option should not be used for panels which are not in a single plane. In addition you may want to redefine reinforcement parameters as the ones you defined are for outdated version of the code.

I tried everything that you proposed and the problem was not solved. I am concerned because there are two  error messages at the table of reinforcement and not zero or none reinforcement

The error stands for the situation when Robot for some reason is not able to calculate the final value of reinforcement in this very location. Unless you have a large concentrated force applied in this point I think it can be assumed that the value of bending moments in this location is similar to the values in the neighbouring nodes. If so you may also assume that the value of reinforcement should be similar too.

Is there any way to overcome the error, because I have to present the maps of the reinforcement and for the node that  the error occurs the value is -10000 

I change the scale from -0,01 reinforcement to max value and this irritating value of -10000 is still there!!

You may  try to change meshing parameters and check if you have the same situation.
