Jul 29, 2021 · 类似的案例，我也遇到过，我的案例是在跑别人的代码时出错的，在出现的“No MRF models present/n No finite volume options present"报错，且后面出现了”Kill“字祥时，其中“Kill”字样很重要。

Jun 23, 2023 · It's only here to inform you there is no MRF model nor fvModels/fvConstraints used in your case. It's perfectly fine, unless you were trying to use one of these functionalities. These are optional features, your solver does not need it to run you case. If the solver crashes, it's related to something else. Don't you get an error when it stops?

Feb 24, 2018 · I am trying to run a simpleFoam model but I am getting a no MRF models present, what could be causing this? The finite volume options present error can be solved by adding a fvoptions file. Also how do you set the convergence criteria?

Oct 9, 2022 · In simpleFoam, you can use MRF models, or finite volume options (fvOptions) to define additional models such as porous zones, source terms, etc... These messages are just stating there is no MRF model and fvOptions for the case you are running, which is perfectly normal as long as you were not trying to use such models.

Jul 3, 2019 · Quick answer: The first thing you can look for in the text is "sigFpe", which you can find in "ZN4Foam6sigFpe13sigFpeHandlerEi". This means that the Signal for Floating Point Exception (sigFPE) was triggered, which usually refers to a division by zero or square root of -1.

Jan 17, 2023 · Hi, I’m currently testing some turbulent flow simulations in OpenFOAM and CalculiX with preCICE as coupling library. I’ve tried to run OpenFOAM with the PISO solver recently, but I’m getting in the following error with…

May 31, 2017 · sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). mpirun noticed that process rank 1 with PID 2840 on node default exited on signal 8 (Floating point exception). Hi Mark, If all the settings are set as default can you make sure that your Rhino units are in Meters? The room is sized based on meters. Dear Mostapha,

Aug 14, 2022 · No MRF models present不是问题. 你这个看起来是壁面函数修正的时候，有0存在。我看你是高超音速。是不是你算的是无粘流。

Apr 10, 2017 · 这个问题困扰了我好几天，本人小白一枚，年初刚接触OpenFOAM，之前做过几次小的模拟没遇到过这种情况，请教各位大神如何解决，感激不尽。 你的质量不守恒。
