Can I ask you something?

How do we calculate the values on the side of the codes in the example I gave?

*SET,_FNCNAME,'HEATFLX'

 *DIM,_FNC_C1,,1

 *DIM,_FNC_C2,,1

 *DIM,_FNC_C3,,1

 *DIM,_FNC_C4,,1

 *DIM,_FNC_C5,,1

 *DIM,_FNC_C6,,1

 *SET,_FNC_C1(1),8625279.2 ! A = Beam power density (pW/um2)

*SET,_FNC_C2(1),-2 ! B = -2 for Gaussian, -3 for Goldak

*SET,_FNC_C3(1),0.0 ! C = X offset

*SET,_FNC_C4(1),-10.0 ! D = Y velocity

*SET,_FNC_C5(1),15 ! E = Y offset

*SET,_FNC_C6(1),1.5 ! F = Beam radius

*SET,_FNCCSYS,12  *DIM,%_FNCNAME%,TABLE,8,16,1,,,,%_FNCCSYS%

 ! ! Begin of equation: A*exp(B*(({X}-C)^2+({Y}-D*{TIME}-E)^2)/F^2)

Hi Hasan

The format of tables from the Mechanical APDL function tool is not documented.  Mike

[Hasan İlker ÇELİKER]

The values in this table are handwritten values. That's why I'm asking.

How were these values written?

My goal is to obtain a temperature distribution as in the relevant video, and then to obtain material depth. I want to remove paint from the surface.

Hi Hasan

No, the values in the table were not hand written.  The video creator used Mechanical APDL interactively to create the equation and evaluate it over a time range.  Then exported it out - the exported APDL text version was then copy/pasted to the WB Mechanical Commands Object.  They just did not show those steps.

See for example this Forum discussion:
