在COMSOl 很多情况系下出现设置内插函数的情况，请问这些内插函数的值都是如何得到的呢？举个例子：CFD...
For unstructured interpolation data, COMSOL Multiphysics may internally apply a scaling of the coordinates of the data points to simplify the process of creating an interpolation mesh. Use the Internal scaling of data points list to control this functionality. Select Automatic (the default) to apply ...

For spreadsheet data, the first columns contain the arguments (typically spatial coordinates); the following columns can contain one or more functions, and the positions entered are the relative position for each function’s data column.For unstructured interpolation data, COMSOL Multiphysics may ...

I have some significant experience with COMSOL. COMSOL is FEM-based. After it has solved a problem using a gross mesh, I can ask for a field value at a given point. This is not a problem and is performed using the basis functions chosen for that particular element. ...

Calling an interpolation functionLogin
Magnus RinghCOMSOL Employee Posted:1 decade ago Hi, That should be possible. Could it be that you define your Interpolation function as a global function under Global Definitions? You should define a space-dependent interpolation function under Model>Definitions. If your interpolation data file conta...
