 April 5, 2005, 21:23 how to get the value in a node #1 caty Guest   Posts: n/a Hello, I want to write a script in POST to calulate an average value of a variable, on a certain plane, across the timesteps. For this i need the value of the variable in each node of the plane. Does anybody knows the comand line for getting this value?

 April 6, 2005, 06:03 Re: how to get the value in a node #2 Rui Igreja Guest   Posts: n/a Hi, Why do you need the value of the variable in each node? You can obtain the average of a variable in a surface as areaAve(variable)@surface . Or do you need a different kind of average? Regards, Rui

 April 6, 2005, 06:16 Re: how to get the value in a node #3 caty Guest   Posts: n/a Hi, this is not what I want. I want to extract data to create a plane. The value stored at a given node would be the average value at that node across the range of timesteps. I don't want an normal average across a plane.

After that I creat another file for the results, empty, txt too. From the command line I areceived the following error: The program was unable to read from the data file. STOP called from routine MGSTOP An error has occured in cfx5interp? Unable to retrive vertex.dat.new from working directory: file not found an error has occured in cfx5interp: the cfx 5 interpolation program existed with return code 1 What does this mean????
