Hello everyone,

I am trying to do the 1D heat transfer analysis of a rod problem with triangular flux along its length(Please refer to the attachment). The problem is taken from "Daryl L. Logan - A First Course in the Finite Element Method".

I have taken the DC1D2 type of element in my analysis and applied the Surface Heat Flux as given in the question.

But after submitting the job I have got the following error message in the console::

Error in job 13_3logan: NO SURFACE FACETS ARE GENERATED FOR SURFACE ASSEMBLY_SURF-1.
Error in job 13_3logan: NO SURFACE FACETS ARE GENERATED FOR SURFACE ASSEMBLY_SURF-2.
Error in job 13_3logan: INVALID FLUX/FILM/RADIATION TYPE ON ELEMENT 1 INSTANCE PART-1-1. LOAD TYPE SPOS IS NOT VALID FOR ELEMENT TYPE DC1D2
Error in job 13_3logan: INVALID FLUX/FILM/RADIATION TYPE ON ELEMENT 2 INSTANCE PART-1-1. LOAD TYPE SPOS IS NOT VALID FOR ELEMENT TYPE DC1D2

As I am new to Abaqus so not able to understand where I have gone wrong. Could anyone help me in rectifying my error?

Thank you in advance for your kind reply!
