How do i use spatial displacement of nodes as displacement values in Abaqus? I obtained the nodal displacement values of (u1,u2,u3) from a bar in an analysis. I want to use these spatial
Hi Sadeq, In the boundary conditions dialog box, there is an option of choosing coordinate system. If you have chosen (the default) global coordinate system, then U1=Global X, U2=Global Y and U3=Gloabl Z. But you have the choice of selecting any of your own coordinate system, in which case U1,U2,U3 will take on those directions. Regards, NSK
• In the boundary condition module constrain U1, U2, U3 at the entire bottom of the part to zero. Apply a displacement of U1= -0.00254 on the other end of the part. • Create a job and submit and run it (it will take some time to complete, as the mesh has 30000 quadratic elements). To edit an existing base motion boundary condition using menus or managers, see Editing step-dependent objects. In the Basic tab, select the Degree-of-freedom to specify the direction for which the base motion is being defined. This direction is always a global direction: U1, U2, U3, UR1, UR2, or UR3.
Abaqus ignores them. If your model is anything similar to figure 3.10 (your attachments), then the boundary conditions at the bottom edge are U1=0, U2=0 and U3=0 ( your Y axis is vertical). All
Abaqus/CAE Usage Load module: Create Boundary Condition: Step: Initial Using the direct format You can choose to enter the degrees of freedom to be constrained directly. Input File Usage Either a single degree of freedom or the first and last of a range of degrees of freedom can be specified.
What is the unit of U3 in Abaqus in the result. degree or radian? I performed quasi-static analysis on gears in ABAQUS. After analysis, I extracted the U3 parameter to measure the gear
Assign restraints (U1, U2, U3, R1, R2, and R3) to joint G, then assign displacements obtained from the global model to joint G through Assign > Joint Loads > Displacements. Analyze the local model for the applied displacement loads. k0zfAm0.
