ANSYS fluent “Floating point exception”,即浮点数溢出,一般在求解器在执行某一算法时,无法进行计算而出现。例如,用某个数去除以零,或者数值超过数值边界等。通常来说,浮点数溢出也说明计算不收敛。以下是几个可以参考,用于解决浮点数溢出的方法。 使用upwind convection schemes upwind schemes引入了数值扩散,但是...

报错7:Error: floating point exception 1.可能是公式里的数值太夸张了,建议用计算器验算 2.operating 气压太大,导致一些物性参数溢出,可以把气压先改小再改大;或者把物性改为定值 3.可在udf对一个数值作限制,避免负数出现(尤其是所有作为商的部分)
“Floating Point Exception”是一个在计算机科学中常见的错误,它表示在执行浮点运算时发生了异常情况。在Fluent中,这通常指的是在进行流体动力学模拟时,由于某些参数设置不当或数值计算过程中的不稳定因素,导致计算无法收敛,从而触发了浮点异常。 2. 阐述可能导致“floating point exception”的原因 网格质量问题:网格形...
SickOfAnsys Subscriber Recently learned how to mesh using ICEM (to a fashion), and export this mesh to FLUENT to solve. Now whenever I use these meshes in my simulation I get the error "floating point exception". This never used to happen when using the standard meshing software in workb...
