Hello, I need to solve a heat transfer problem in four adyacents regions that have different initial temperature. Can I implement this in FlexPde? Thank you very much in advance |

Absolutely. You an set the initial temperature in each region as well as the boundary conditions. |

Initial values are specified, not surprisingly, in the INITIAL VALUES section. See the Help chapter "Problem Descriptor Reference | Sections of a Descriptor | The INITIAL VALUES Section". Or look under "Initial Values" in the Help Index. Or look at one of the more than 80 Example files that include INITIAL VALUE specifications.

Looking at your previous postings, I infer that your question is really how to specify conditions that vary with region. Do this: 1) in the DEFINITIONS section, give a name to your inital value, such as TEMP0. 2) in the INITIAL VALUES section, declare the initial value: INITIAL VALUES Temp = Temp0 3) in the various regions of your problem, declare the values to be assigned to TEMP0: Region 6 TEMP0=98 ... Region 7 TEMP0=99 and so forth....
