Hi, you can write something like the following:

[nupdate = 10] ;

def install

whilestepping

if nstep < nupdate

nstep = nstep+1

else

...

nstep = 0

endif

end

Best regards,

 Dear Huy Tran-Manh ,

When I import a  geometry from autocad (dxf) to flac, the software always shows Extracted no quad blocks- canceled. Can you please tell me how to solve this problem?

I will really appreciate it if you can recommend some files about Autocad-to- Flac 2D.

As for my question,pls see the attached file.

Kind regards. 

Dear Yang,

You can add two vertical lines from two bottom corners of your foundation (I suppose) to the bottom line. You have three rectangles which are all quad blocks.

Best regards,

Dear Huy,

Thanks.

I  add two lines in autocad, but it still shows the problem in flac.

It has been two days since I started to solve this problem, and i really puzzled.

Meanwhile, the manual also has not talk about it much.

I really appreciate your help.

Best regards.

Have you try to clean up it. You can send me the dxf file? Which vesion of Flac you have?

Dear Huy,

I really appreciate your kind help and will send the files to you immediately.

Thanks.
