View Full Version : Node coordinates issues in ABAQUS?

Hi All,

I create part instance in assembly process in ABAQUS and do some movement and orientation of the instance. So the part instance coordinates now are difference from the original coordinate of part itself.
Then, I mesh on instance(not on part), create input file. Abaqus gives me the original coordinate of part not the coordinate of part instance that I expected.

For example,
*Assembly, name=Assembly
**
*Instance, name=layer1-right, part=layer1
-8.265812, -0.00958899999999896, 0.5
-8.265812, -0.00958899999999896, 0.5, -8.265812, 0.697517811231782, 1.20710681123178, 180.
*Node
1, -9.41482067, -0.0750161856, 0.0124347778
2, -9.41482067, -1.90384671e-05, 0.0130892675
3, -9.22078228, -0.0191434566, 0.0129223717

but coordinate of node 1, 2, and 3 of my instance all are in positive not negative values.
Let say my instance node coordinates are:
node 1, 0.0, 0.0, 0.0
node 2, 0.0, 0.3, 0.5
node 3, 0.0, 0.4, 0.6

My point is I want to search for some nodes that match my conditions such as find all nodes whose x values are zero. If input file gives me node coordinates of instance, it can be done easily.

What should I do to overcome this issue?.

Thanks in advance.

I would do the same mathematical transformations that are defined as part of the *Instance command.
I don't see a easier way.

Dr.Jorgen,

I don't understand what Abaqus tells us about this:
*Instance, name=layer1-right, part=layer1
-8.265812, -0.00958899999999896, 0.5
-8.265812, -0.00958899999999896, 0.5, -8.265812, 0.697517811231782, 1.20710681123178, 180.
