Hello,

i would like to use FePest to estimate hydraulic conductivity and van Genuchten parameters. Unfortunately, the parameter list in the the FePest interface does not offer alpha or n. Only a parameter called "Unsaturated-flow model type". Since this is a category in the Feflow setup and not a single parameter i am wondering if i have an mistake in the setup.
Is it possible to choose alpha and n in the FePest interface for estimation?

Thanks for helping

the time series are right like this. 50 and 250 is existing and the .pow files are also properly imported and displayed in the time series menu. I actually discovered that one datapoint is always displayed in the scatter plot. But it is just only the current one in each time step.
I am doing the scatter plot now with excel but it is kind of nasty to calibrate the model. Would be nicer to have it directly in feflow without exporting and importing.

      1      50.0000000000      15.9300000000        1      -1  L25      400      250        0.2500000000
      2      30.0000000000      16.6450000000        1      -1  L5      400      50        0.2500000000

That's the entire file.

I am wondering if the reference timelines of the observation points would be displayed automatically in the hydraulic head chart. For me this is not the case.

Thank you for your fast answer.
I checked the "edit observation points", and all observation points are set to active. Also, i changed the confidence interval to 0. I am wondering if maybe something is wrong with my observation points? I don't get the observed values automatically plotted in the hydraulic head chart. I always need to import them from the .pow file. So maybe the scatterplot can't be produced because it doesn't find the data.
However, in the observation point settings the timeline is connected to the observation points. Do i need to connect them somewhere else again?

Hello there,

i am having problems with the scatter plot. When i activate the scatter plot via right click on the hydraulic head chart i don't get data in the plot. Only a vertical line appears. I saved the scatter points to a .pow file and it only contains 2 values.

Thanks for answers in advance.

The problem is not caused by the super mesh. I also tried the generator with a simple rectangle and it showed the same error message.

The error message is "unspecified error". Unfortunately there is no detailed error message. Just this.
I already reinstalled it and updated all graphic drivers on my PC. But the error is still occurring. Also for the two other grid generators.

Hello,

i am using Feflow 6.109 and i get an error message when i try to generate a mesh using the generator. I installed the Triangle mesh generator according to the instruction but it brings me the error message anyway for all.
Does anybody could help me with this?
I am working on Win 7/ 64 bit. The error is appearing in both Feflow versions (32 bit and 64 bit). The mesh should be generated for a simple polygon, nothing more.

Thanks in advance
Ludwig
