Dear all,

I've a question about heater CONVECTION and RADIANT tubes: this part of the heater is not governed by the ASME B31.3 but by API 530, consequently I think CAESAR is not the best way to analyze this systems.

Anyone has experience of furnace coils analysis? Which program is used for this kind of job? (maybe a finite element software is the best approach?)

NOTE: Analyzing, for example, a convection coil with CAESAR II one of the major problem encountred(my experience) is the friction that doesn't allow the convergence of the solution, so it must be omitted for a considerable number of supports, altering the precision and the relibility of the results.

Someone agree with this statement?

Thanks in advice.
