Hi
I have some questions when I use Feflow to simulate.

My model is a simple ideal model.

It have four layers,  1 layer represents an  impermeable layer , 2,3,4 layers represent one aquifer including three parts with different hydraulic parameters, which reduce from bottom to top.

My domain is dry at the first time, and have a influx at 5 slice from a well(set it as well boundary constrain) .

1 slice is set by free&movable, 2,3,4 are unspecified and 5 is fixed.

The results of simulation have something wrong with water table of tow slices. The highest water table of 5 slice was on the well point and reduce to round, but the 4 slice was the opposite for the lowest water table was on the well point. 3 slice was the same with 5 slice and 2 slice was the same with 4 slice.

What wrong about that, or on my model?

Thanks for help.

Can anybody tell me, beside "IfmGetFlowValueOfGroupIdAtCurrentTime(pDoc,0)" and "IfmBudgetQueryFlowAtNode", are there  other API function which can calculate the flux for several nodes?
And when using  "IfmBudgetQueryFlowAtNode" and "IfmBudgetFlowCreate" , should  the callback is a 'PostTimeStep' ,can't for the "PreTimeStep"?

Can anyone help me?

In a groundwater system, a aquifer would transform from unconfined aquifer to confined aquifer, how to carry out that? which parameters should I setting?

When I calculated the flux flowing into rock from tunnels in a mine, using the function"IfmGetFlowValueOfGroupIdAtCurrentTime(pDoc,0)".But when the tunnel head get higher, the flux will larger than the tunnel's total volume. Althrough hydraulic gradient become bigger, but it shouldn't make the tunnel head become a negative number,  I thinks there are some wrong with the data,but what's wrong? Does somebody know?

Are there other ways to calculate the flux? I get the nodes number of the border.
Hope someone help me.
Thanks!

Thank you for reply!

I had another qustion,and hope you can help me.
When I run feflow coupled with my code ,

for(i=0;i<non;i++)
  IfmSetBcFlowValueAtCurrentTime(pDoc,node[i],H2);

there were many errors like this"W 12/29 17:10:16 C:\Program Files\WASY\FEFLOW 5.3\bin32\feflow.exe[3376]:
Moxing1: SetBcFlowValueAtCurrentTime: At this node no boundary
condition is imposed! Skipped..."
But I defined the boundary type as the first boundary(given the water head),what's wrong with that?and how to modify that?

Thank you!
I got it! :)

But now I has another question. when I used the function(IfmGetResultsFlowHeadValueAtXYZ(pDoc,x,y,z,*ine)), how to define the parameter(*ine)?When I define it 0, it showed some mistakes.

And the other API functions also have the same question, I didn't know how to define some parameters, and the software doesn't show the details about them.How can I do?

Who can help me? ??? ???

I made a program to calculate the head,but it seams that the program didn't work, and I'm not sure that.How can I do?
If I use the following code to show the results:
"static char str[200];

sprintf(str,"h=%e\n",h);
IfmDebug(pDoc,10,str);
"
Where do the results show?

Can the program has subprograms?

Thanks a lot!

Can anyone help?

I want to simulate flow in a mine to get the water level, but how to build the geologic model with the tunnels?
And how to do with some fractures?

Do you just mean the "reference data->reference distribution"?Or the "Reference data->observation point group"?Which one  would I choose?
