Enhancements

Cloud Sign-in Licensing

Sign-in licensing now uses the system browser for a smoother authentication experience. Remote check out licensing has also been added for dark site or air-gapped machines that do not have internet access.

Import and Export

CSiPlant files can now be exported as AutoCAD .dxf files and can be opened in nearly all CAD programs

Analysis

The rotation of link-element local axes with large displacements is now controlled by the P-delta factors defined for the link property. This new behavior enhances behavior for nonlinear static, direct-integration, and staged-construction load cases where the geometric nonlinearity parameter has been set to "P-Delta plus Large Displacements".

Analysis

Support objects were enhanced to allow the user to apply the effects at the centerline of the pipe to which they are connected, rather than always applying the effects at the surface of the pipe.

Documentation

The CSI Analysis Reference Manual has been updated to include content for minor existing features that were previously only described in the Help and to improve the ability to search within the PDF file.

Piping Design

Handling of ASME B31J is enhanced, giving the ability to control when to apply Note 3 from Table 1-1. This is applicable when calculating the flex factors for 90 degree bends and elbows that match the thickness of the adjacent pipes.

Piping Design

B31J – 2023 code enhanced to include a modification factor that accounts for large aspect ratio components.

Piping Design

ASME B31.12- 2023 has been added.

Drafting

Users can now select tees in the model based on the assigned tee type.

Cloud Sign-in Licensing

Cloud Sign-in licensing is now available• Access CSI software using secure user credentials — no more activation keys• Access licenses anywhere with internet access• Option to create License Groups to manage who has access to your licenses• Option to remotely terminate an active license session• Option to federate your identity provider (IdP), allowing users to use their familiar company credentials insteadCloud Sign-in Licensing Details
