| MotionSolve |
Highlights
MotionSolve is a state-of-the-art multibody solver available in HyperWorks. It has a complete set of modeling elements and powerful numerical methods to support a full set of analysis methods. The accuracy, speed and robustness of MotionSolve have been validated through extensive testing with customer models and test data. MotionSolve also offers unmatched compatibility with ADAMS/Solver input.
In version 2017.1, MotionSolve brings new capabilities, added functionalities to the existing capabilities and improvements in performance.
Resolved Issues
NLFE bodies and compliant joints
Previously, MotionSolve failed to run if all the joints defined on an NLFE body were made compliant. This is fixed with 2017.1 such that you may define any kind of joint on an NLFE body and successfully simulate the model.
Defining JFLOAT marker on NLFE bodies
In MotionSolve, you cannot define the JFLOAT marker on a flexible body, such as the NLFE body. Previously, if you did so, the solver would fail without an appropriate message. With 2017.1, an appropriate error message has been added that can help you debug your model and remove any JFLOAT markers defined on the NLFE body.
Difference in extrapolation results between FIESUB 810 and FIESUB 910
In 14.0.230, it was reported that extrapolation results between field subroutine FIESUB810 and FIESUB910 are different when expected to be the same. This behavior has been modified with
2017.1 such that both subroutines produce the same extrapolation results.
Eigen modes not orthogonal
It was reported that the eigenmodes are not orthogonal using 14.0.230. This has been fixed in 2017.1. The eigenmodes calculated now are orthogonal.
PINVAL affects eigensolution
In 14.0.230, it was reported that use of the expression PINVAL affects the eigen solution. This has been fixed in 2017.1, the use of PINVAL no longer changes the eigen solution.
KE function
The KE function that calculates the kinetic energy of a rigid or flexible body was scaled incorrectly. The scaling has been corrected with 2017.1.
| AcuSolve |
Highlights
AcuSolve v2017.1 further improves Altair’s class leading solver technology. The current release includes significant fundamental improvements to multiphase capabilities, enhancements to distributed scripts and improved material modeling.
Improvements to Multiphase
In this intermediate release we continue to build upon our initial multiphase offering by significantly improving stability and accuracy. While still considered to be a Beta feature multiphase in AcuSolve is steadily improving to handle more industrial-level cases.
AcuTherm
Data can now be output per element from acuTherm by specifying the command line option –to abaqus.
AcuProbe
Variable lists have been reorganized by type for better readability and navigation.
Notable Changes
- Added support for Piecewise-Bilinear fluid properties
- acuLiftDrag script has been added to the distribution, available in the bin directory
Resolved Issues
Resolved a segmentation error with acuMeshSim involving mixed topology extrusion meshes and mixed topology boundary layer meshes.
