good day..

im running an analysis which involve gravity loading/body load.

but I not sure what to input the value of X and Y at the curve editor and what the relation these curve with the gravity effect to the analysis....thumbnail attached..

Hi,

X component defines the time and Y component defines the magnitude of the load.

Thank prakash for reply.. But i little bit confuse how can i set the time and load..?? I already set the gravity acc. as 9810... then what time and load must i put on that graph..??

The way you put on the graph is right. You deifne the vector and magnitude in BCs and define the function.

Prakash value 10000 you put on the table meaning is 10000s.?? And 1 meaning 1N..??

it all depends on what units you are using for your model. HyperMesh is unitless.

Please maintain unit consistency.

How to give a function in curve editor. like e*x or some complex function.

I have some result which i get from some experiment how to input it in system ?

Hi,

Try with XY Plots option in the tool bar. Use the Edit Curves panel to create new curves or edit existing ones. Each vector can be defined using either a data file or a math expression.

Please go through the attached document which explains the same.
