Why do many errors appear when I compute the parameter U1?

[zhemu26]

[ww3_multi.inp.txt](https://github.com/user-attachments/files/23700254/ww3_multi.inp.txt) [ww3_multi.out.txt](https://github.com/user-attachments/files/23700255/ww3_multi.out.txt)

When I choose to calculate the parameter U1 in the ww3_multi.out file, the process gets stuck at this point, as shown in the last lines of ww3_multi.out. Alternatively, I encounter an error message like [qhcn148:605033:0:605033] Caught signal 11 (Segmentation fault: address not mapped to object at address 0x10). Meanwhile, the out_grd file is generated with a few MB of data and then stops outputting. Could you please help me understand what is happening here?

Dear zhemu26,

You should allocate more memory to avoid your run to blow up

Thank for your reply!
I am trying to define a new output parameter, which represents the energy loss obtained by integrating the sbt term in the point output. I want to define this parameter in the code so that it can be output for the entire domain. I have only added the code related to the calculation of the parameter in the subroutine W3OUTG of w3iogomd.ftn file, but how should I allocate memory for it?
