Applying Load at nodes in Abaqus

Applying Load at nodes in Abaqus

Applying Load at nodes in Abaqus

Dear all,

I would like to apply a concentrated load at each node (loads are different). The total number of nodes is more than 32000.Can any suggest any method to do that?

RE: Applying Load at nodes in Abaqus

What kind of information do you have? Load value per location? Then you could map the load onto the region.
In the Load-Module go to Tools -> Analytical Field.
See documentation for details.

RE: Applying Load at nodes in Abaqus

If regions of application for different loads can be easily distinguished then you can create sets containing nodes belonging to specific region (single set has nodes that will be subjected to the same load). Abaqus provides some methods to aid set creation for large number of nodes (for example by angle and by feature edge seldection in CAE as well as tools available for scripting). Then assign this sets to *CLOAD keywords with proper values of concentrated force. This could be automates as well.

RE: Applying Load at nodes in Abaqus


I have given the load on to the region by using CLOAD. The load will be changing in each iteration and has to be applied at the nodes. If I can give the nodenumber, load, direction as the scripting input I can try to apply the different load at different nodes. But Abaqus is allowing only pickedset, load, direction. If I edit the script and give the node nuber it showing the error that the mesh does not exist and the concentrated load will be ignored

RE: Applying Load at nodes in Abaqus

You can use the node number, but you have to be careful when using the input file format with parts and assemblies (active by default). Here the node numbers are changed internally to consider this method.

In A/CAE you can define to not use that file format. Then the node numbers will not be changed internally.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
