Support for 64-bit Microsoft Windows® and 32- and 64-bit Red Hat® Linux®
operating systems for all analysis types -
Previous releases of ALGOR software have supported 64-bit Windows for linear static stress analysis.
Now, V19 expands ALGOR's multi-platform support,
allowing users to apply the power and speed of 64-bit Windows and 32- and 64-bit Red Hat Linux
operating systems to all analysis types
including static stress and Mechanical Event Simulation (MES) with linear and nonlinear material models, linear dynamics,
steady-state and transient heat transfer, steady and unsteady fluid flow, electrostatics and full multiphysics.
This expanded multi-platform support will allow users to analyze larger, more complex models faster than ever
particularly for computationally intensive analyses such as nonlinear MES, fluid flow and multiphysics.
The next release will support 64-bit UNIX workstations and future releases will support distributed processing.

Boundary layer meshing -
In fluid flow analysis, the greatest changes in velocity typically occur
where the fluid interacts with boundary surfaces.
A fine mesh is needed in these areas in order to accurately simulate flow behavior. V19's new boundary layer meshing capability
allows you to simply choose an option in the "Model Mesh Settings"
dialog that will automatically generate a finer mesh near the surface while keeping a coarser mesh throughout the rest of the fluid domain.
Thus, you can easily and quickly
create a finite element mesh that is optimized for accurately
simulating the detailed behavior of fluid flow along its boundary. The image
shows a fluid domain mesh (the red part) inside an irregularly shaped
solid boundary with a highlighted close-up view of the detailed mesh
along the boundary.

Exporting to the HOOPS Stream File (HSF) format - In ALGOR V19, a model's
visualization data can be exported to the third-party HSF format for sharing with other engineering applications.
For more information about the HSF format, visit the OpenHSF Initiative website.
The image shows how, in the Superview Results environment of FEMPRO, a
model's visualization data can be saved in the HSF format.

Direct CAD/CAE data exchange with Rhinoceros -
V19 provides improved support for Rhinoceros with the implementation of InCAD technology that allows Rhinoceros users to
simply choose a built-in menu option for directly transferring a CAD model to ALGOR for analysis.
The image shows a model that was built in Rhinoceros and analyzed in ALGOR.

Running an analysis on a remote computer - V19 provides options
that allow you to run an analysis on a remote computer.
For example, you can set up a model on a Windows PC and then analyze it on a networked 64-bit Linux PC to take advantage of its computational speed and power.
Shown here are FEMPRO dialogs for specifying remote execution on a Linux PC.

Complete Superdraw III sketching functionality in FEMPRO -
In V19, all Superdraw III sketching functionality is available within FEMPRO.
New functionality includes 3-D sketching options such as rectangles, circles, splines, inquire options and more.
Now, you can perform all of your 2- and 3-D sketching, modeling and meshing directly within FEMPRO
as illustrated by this image of a belt drive assembly.

Equal-order segregate solver - V19 provides a new equal-order
segregate solver for transient fluid flow and coupled fluid flow/heat transfer analyses for faster runtimes with less memory.
The new solver's segregated solution method breaks the global matrix
into smaller sub-matrices, which are then solved quickly while using less
computer memory. The segregate solver is recommended for large models (i.e., 100,000 degrees of freedom
or more) or
when other solvers experience slow convergence.
The image shows how, on the "Options" tab of the "Analysis Parameters" dialog,
options can be specified for the new equal-order segregate solver.

Loosely coupled fluid-structure interaction -
New in V19, results from a fluid flow analysis can be input as loads for
a static stress analysis or MES by simply using an option on the "Analysis Parameters"
dialog to specify the fluid results file. This loosely coupled
fluid-structure interaction allows you to analyze the effects of fluid
flow on a structural system. For example, as shown in the image, nodal
reaction forces that were calculated during a steady fluid flow
analysis were used as loading in a subsequent linear static stress
analysis.

Displaying fluid flow results during analysis -
In V19, while a fluid flow analysis is running, results for time steps already solved can be examined in the Superview
Results environment of FEMPRO. As shown in the image, this improved results display capability allows you to
examine fluid flow results while the
solution is still running in order to verify that the fluid flow solution is
proceeding as desired and determine whether or not to stop the
analysis before completion or let it run to the final time step.

Power spectrum density output at nodes - In V19, for linear dynamic analysis,
power spectrum density (PSD) values are calculated and output for the nodes of a model.
This new capability allows you to create graphs of PSD nodal values as shown in the image. |

2-D stress linearization utility - New in V19, the stress
linearization utility of the Superview Results environment can be
used with 2-D models including axisymmetric models. You can use the stress
linearization utility to define a Stress Classification Line (SCL)
through the model and then the software automatically calculates the linearized stress distribution
and formats results for easy comparison with code requirements (see the image).
Thus, the stress linearization utility helps engineers easily evaluate their designs' compliance
with industry standards such as the ASME Boiler and Pressure Vessel Code (BPVC). |
