Hi Rajesh, Take a look at the M_ins and T_ins options on the SECDATA command; it allows you to specify a material property and thickness for the buoyancy material (ANSYS calls it insulation). Using this increases your hydraulic diameter, too.

I want to determine a tension offset envelop (TOE) for a drilling riser. I have configured top tension riser using PIPE288 element with internal external fluid command, ocean current, applied riser dry weight in riser section and adjusted buoyancy load included with the riser dry weight. I used APDL command to apply the ocean current for the analysis. I compared the result with Riflex software result but the result was not good enough with the increase of current intensity. Riser was not much effective with the increase of the current intensity. As I applied ocean current load riser only, it may not the real configuration of the riser because riser included with the buoyancy material can increase the drag area for ocean current. Is there any advance tool or command available in ANSYS which can included buoyancy module surround the riser and also will calculate for the ocean current load?

Adriana, radiation ray tracing is (to some extend of CFX, FLUENT and recently HFSS for electromagnetic reflection) a feature within ANSYS Mechnical's thermal capabilities. If you need reflect some entrant wave back to a radiating or other body, you can do that, as far as I recall. At least as long as heat transmitted via radiation offers output suitable for the optical wave too. I seem to remember that ANSYS has some limit build in wrt the wave frequency range.

Well, well, one should never stop exploring new things. I was asking around if people know of any Ansys software that can model optics ray tracing. That doesn't mean I could not do it if there is one such software even if I am a thermal engineer, because I am more than that. I am doing lots of Multiphysics simulations which involve lots of different softwares. Concept wise, what is that terribly difficult about the theory of optics? I may not know it just yet, but one can always read, right? Long term contractors we will not hire, maybe we could outsource only that portion of the project but that is it....not anything else.
