CSI Perform3D 10.1.0 (1427)

Computers and Structures, Inc. (CSI) is pleased to announce the availability of CSI Perform3D 10.1.0 (1427). Perform3D 10.0.0 and 10.1.0 add new reporting and an API to programmatically interact with models. Additional database tables have been added and the analysis engine can now be run with multithreading to improve performance.

Perform3D 10.1.0 Release Notes - Date: 7-Feb-2025
Below lists changes made to Perform3D since v10.0.0, released 11-December-2024. Items marked with an asterisk (*) in the first column are more significant.

11163 Two functions are added to the Perform3D API: cStructureModel.GetProgramInfo retrieves the program version and level and cStructureModel.GetVersion retrieves the API version number.
* 11121 An incident was resolved where the analysis process would unexpectedly terminate for certain models with a large number of nodes (e.g., more than 30,000). When this occurred, the GUI would continue to wait indefinitely for the analysis to finish unless the user manually stopped it.
11156 An incident was resolved where API function cGroups.GetAllGroupElements returned an error code and did not get the element numbers for a specified element group.
11158 An incident was resolved where the API function cNodes.AddNode would fail to add the 200th node in the model and subsequent API calls to modify the 200th node, including adding mass through cMasses.AddMasstoNode, would fail.
11202 An incident was resolved where the parameter weightPerUnitLength in the API function CompoundComponents.AddBeamColumnCompoundComponent did not change the weight of the component.
11130 An incident was resolved where the extruded display of 2-node elements (enabled by going to Options menu>Display Options and selecting "Extrude 2-Node Element) may be incorrect for elements where the units used in the component properties were different than the model units. This was a display issue only.
11088 An incident was resolved to display information about network license.
* 11099 An incident was resolved where, when a new nodal load pattern is added (Load Patterns task, Build phase) in Perform3D v10 so that the model has more than two nodal load patterns in total, an error message would occur when trying to save the model and the model could not be saved until the newly added load pattern is deleted
11120 An incident was resolved where an Abnormal Condition error occurred when going to the Database Tables (Tables menu>Show Tables) in a structure that has no nodes.


Perform3D is a structural-engineering software useful for the performance assessment of structural systems. State-of-the-art constitutive-modeling capabilities enable characterization of material nonlinearity, including strength and stiffness degradation during component-level hysteresis. Analysis capabilities also extend to geometric nonlinearity and effects associated with P-Delta behavior. Advanced modeling tools enable a sophisticated simulation of structural behavior. Components may be grouped according to type, location, and limit state before evaluation proceeds in terms of strength or deformation-based demand-capacity ratio. The dynamic display of D-C usage is available through color-coordinated time-history animations. Perform3D is an ideal tool for nonlinear performance-based analysis and design, created by Dr. Graham H. Powell, University of California at Berkeley Professor Emeritus of Civil Engineering.
