hello guys,

 

i am doing some AcuSolve tutorials by Engineering Solutions-AcuSolve.

 

I have found some problems with the Transient-heat-transfer while using on HyperMesh-Engineering Solutions.

 

Here they are:

 

1. I can not restart computing on Engineering Solutions:

The mentioned simulation is transient, which require a restart computing base on the previous computed results ( Steady-state). but restart function seemed not intergrated in Engineering solution.

 

2. Cant assign multiplier function for inlet's temperature: 

to be more precise, the inlet temperature drop down in few seconds. but this cant be specify in HyperMesh-Engineering solutions.

 

Does anyone know about this issues? Please help. 

For more informations, please ask.

 

Appreciated!

    Multiplier function is available for Simple Boundary Conditions. Advanced option needs to be activated first.  

    Could you please explain what issue did you exactly encounter while selecting mulitplier function?

    The restart function is currently under implementation for HW-CFD.

     

    Meanwhile if you wish you can restart by exporting the .inp file first, then using AcuSolve Cmd Prompt  for restarting (using the previous results). 

     

    See this link for details on how to restart using Command line.

    thank you for your instruction. 

    As the picture i posted, there is no 'Show advance feature' in the 2017.2 Version.

     yours is 2017.3.

    I will update my version to solve the problem.

    -thanks again,

    -appreciated your helps,

    -i have read given links and AcuSolve Commands Reference Manual but it make me very confuse.

    -could you help me more?

     such as a simple form of restart command. 

    thanks in advance! :D/emoticons/default_biggrin.png' srcset='/emoticons/biggrin@2x.png 2x' title=':D' width='20' />
