Hello everyone, I defined a computational model through a .m file function. The function takes the random input X and gives the output Y. In the .m file, I define a UQLink model (which links UQLab to a FEM software) and I use the result of the FEM analysis (the FEM result is extracted thanks to a parser and is a scalar) as input for another computation which is implemented in the .m file. So the output Y is dependent on my FEM result and from other computations performed in the .m file. The problem is, that a new UQLink model is created each time the .m file function is called (at the end of the analysis I have in the folder many .mat files and .zip files called Model1, Model2, …, ModelN). Is there a way, to define the UQLink model outside the .m function and pass it, so that I only have to keep in the .m file the line which starts the FEM analysis? Something like: `function Y = myFunction(X,myUQLinkModel)` `...` `FEMresult = uq_evalModel(myUQLinkModel,X)` `Y = f(FEMresult)` `end` Another problem I have, is that if I perform an AKMCS, even if I limit the max added samples, say MaxAdded = 30, it runs forever and doesn’t stop. But I don’t know if it is related with the problem of having a new UQLink model each time the function Y is called. Thank you! ---

Hi @Gil You can do what you suggested by passing the UQLink model as parameter of your myFunction model. Basically it would go like: ``` Mopts.mFile = 'myFunction'; Mopts.Parameters = myUQLinkModel ; myModel = uq_createModel(Mopts); ``` Then you can define your model exactly as you have suggested: `function Y = myFunction(X,myUQLinkModel)` `...` `FEMresult = uq_evalModel(myUQLinkModel,X)` `Y = f(FEMresult)` `end` The UQLink model is defined in the main configuration file of your analysis, prior to defining `myModel`. I think with this change you shouldn’t anymore have multiple models defined. Generally speaking, also remember that when you have to build a model repetitively in UQLab (which is not the case for your problem here), you can use the options ’`-private'` as in `myModel = uq_createModel(Mopts,'-private');` to avoid saving in memory intermediate models that were built throughout the analysis. For UQLink, you can also use the `.Archiving` option to clear the files created during the FE analysis. Regarding the AK-MCS issue, that is a bit weird and I can’t reproduce the error from my side. Could you please try again with the updates above and let me know if you still have the same issue? Cheers, Moustapha ---
