I am solving a coupled moving heat source-diffusion problem using SOLID227. I have a simple cuboid geometry with heat source moving along the center. For moving heat source boundary condition, I used this plugin Moving Heat Source.

But I needed to solve the thermal-diffusion model. So I used the following APDL in geometry and solution.

Geometry :

ET,matid, SOLID227
! for thermal-diffusion DOF
KEYOPT,1,matid, 100010

Transient Thermal Solution:


alpha_c = 0.02
cem_c = 6.67

! assign couboid nodes as alternate layers of concentration.
x = nx(currNode)
region = mod(nint(x/lambda),2)
currNode = ndnext(currNode)

!named-selection for boundaries


Ea = 237207.4
R = 8.314

But I am not able to get any results. And no helpful errors are shown in solver output. Can someone please help me what's wrong in the above setup?
