the accuracy number

[mapi]

Hi,
When I look at the result (e.g. displacement), there is only four digital number. How can I get more number?

Thanks.

How many random numbers do you want ?

FEA is NOT an exact science, it is an approximation.

Four digits are probably too many quote.

Right. But I just want to know if we can get more digits and how. A little curious.

You can use
- CAE->visualization->Report
and output to displacement field to a file. The program lets you to adjust the number of significant digits to be used for the output values.
- ABAQUS Scripting Interface to obtain the values with the full number of digits:
Open the .odb file, let's say my_odb.odb:

frame=session.odbs['C:/Temp/my_odb.odb'].steps['step_name'].frames[frame_number]
values=frame.fieldOutput['U'].values
for iVal in values:
print iVal.instance.name, iVal.nodeLabel, " U1=", iVal.data[0], " U2=",iVal.data[1], " Magnitude=",values[0].magnitude

You should set 'C:/Temp/my_odb.odb' , 'step_name' and frame_number according to your needs.

If you are referring to the number of digits visible in the contour legend... then just go to View - Viewport Annotation Options - and in the Legend tab you'll find a bunch of options for format (Engineering, Scientific, Fixed) and the number of decimal places.

Thank all.
What do I do if I want to control the number of digits in input.inp and see the results in the job_name.dat?
