Temperature-time curve problem in thermal transient analysis

Temperature-time curve problem in thermal transient analysis

Temperature-time curve problem in thermal transient analysis

(OP)
Hello,
I am using ANSYS (classic R9.0) doing a simple thermal transient analysis, and have problem with temperature over time curve. The curve is not start from 0 second, so the temperature does not start from my B.C. temperature. It looks like the first few substeps are not recorded. Anyone can tell why? and how to fix it?

Thanks!

RE: Temperature-time curve problem in thermal transient analysis

You'll probably need to rebase the "time" column of your time history back to zero, since at the start of the transient step ANSYS will use the "time" column as a lookup table for the loads within the step. Easy enough to do.
