Multiple formats are allowed on the same entry; these should be comma separated. The problem set up is simply done by defining the design region, the maximum bead depth and the draw angle. However, Altair Engineering OptiStruct 13. It can clearly be seen, they match perfectly with the original model's results. Treatment of very stiff members as being rigid elements eliminates the ill-conditioning associated with their treatment as ordinary elastic elements. For example, if you consider the case of a pickup truck, various cabin shapes can be solved for, by allowing the bed and the chassis to remain unchanged. Modal Frequency Response Analysis Loading Frequencies are parallelized.

If G1 through G4 are specified, then an impedance is associated with the quadrilateral face. All other marks are the property of their respective owners. The static equilibrium is given as: 2 The eigenvalue problem for a normal modes analysis of the body using a diagonal mass matrix represents itself as: 3 The task of the component mode synthesis is to find a set of orthogonal modes represent the displacements u of the reduced structure such that: that Where, q is the matrix of modal participation factors or modal coordinates which are to be determined by the analysis. X into a set of Craig-Chang Method This method uses a system that is unconstrained free-free and therefore has six rigid body modes. Due to the specialized nature of these results, some explanation is required regarding their meaning. The total length of information on this card is limited to 200 characters including the card name and spaces between arguments.

Corner grid points G4, …, G6 must be on the top face with G4 opposite G1, G5 opposite G2, and so on. In such scenarios, using a lower value of this run option or not using it at all , will result in a lower use of memory and may improve overall speed an response time. . If the orthogonal modes are normalized with respect to the mass matrix M, the reduced matrices for the subsequent analysis appear as: 366 OptiStruct 13. If the user-prescribed node numbering on the bottom and top faces is reversed as compared to the sequence shown above, then the nodes are renumbered to produce right-handed orientation of numbering. No default topn Specifies that only the top N values should be output.

Tensor format is used for H3D output. This entry is represented as an optimization objective in HyperMesh. The new release also provides similar amounts of enhancements for its market leading optimization technology. G4, …, G6 must be on the top face with G4 opposite G1, G5 opposite G2, and so on. Acceleration output is only available for frequency response and transient analysis solution sequences. If G1 and G2 are specified, then a line impedance is assumed.

This card is represented as a spring or mass element in HyperMesh. The moments of inertia are defined as follows: The beam coordinates must be aligned with the principal axes of the cross-section. They are also highly desirable in biomedical implants due to their porous nature and the ability to facilitate the integration of tissue with the trabecular structure. Note: A residual run with a large Craig-Chang super element should be run in either Lanczos or the Direct method. Only one scalar mass element may be defined on a single entry. This information is stored in the. {cardname}: Only bulk data entries with the given {cardname} are echoed to the.

The number of solutions selected will always be equal to the number of quantities in the selected set. The element set identification number is the only input required for this entry. Multiple formats are allowed on the same entry; these should separated by a comma. The critical response points must be independent points. Real A Area of the beam cross-section. In an automated assembly process, usually all bolts are pretensioned simultaneously. Linux Note: Altair Engineering OptiStruct 13.

Component modal synthesis strain energy output is only available for frequency response analysis both direct and modal methods. There are still some size limitations as a result of the size of standard integer variables, but they should only occur in very rare cases. The entire model is divided into parallelizable subcases, Table 2 lists the various supported solution sequences and parallelizable steps. Note that this modal damping energy only includes the energy contribution from viscous dampers. Supported Solution Sequences OptiStruct can handle a variety of solution sequences as listed in the overview.

For optimization, it contains the design variables, responses, and constraint definitions. In the case of a subcase that is not a geometric nonlinear analysis, these extensions are ignored. However, all solution sequences do not lend themselves to parallelization. OptiStruct Configuration File All options for memory control can be specified in the OptiStruct Configuration File, however, this is not advisable if the configuration file is shared on the common file server. Variables can be assigned to perturbation vectors, which control the shape of the model. Scalar mass elements are ignored in heat transfer analysis. .
