What’s New

CAD Sync: ( PRO and TEAM subscriptions ) 
OnScale Solve’s new CAD Sync functionality dramatically improves the Design and Analysis workflow.  With CAD Sync, when you import your CAD geometry from Onshape, you can automatically update the geometry in OnScale Solve while retaining all the simulation features like materials and loads that have already been applied to the geometry. You no longer need to re-import your Onshape file and redefine all your analysis settings during the iterative design process of modifying geometry and analyzing simulation results.  Once you set up all your parameters in OnScale Solve to run a simulation for mechanical, thermal, structural-thermal, or fluid flow analysis, you can make a change to the geometry in Onshape based on your simulation results and click CAD Sync to update the geometry in OnScale Solve.  

Why is this important to you?

CAD Sync is a one-click operation that keeps your connected Onshape CAD geometry in sync with any existing simulation settings in OnScale Solve such as materials, suppressed parts, restraints, forces, temperature settings, inlets, outlets, and more.  In a typical Design and Analysis workflow, you may need to iterate dozens of times to get to a final optimized product.  OnScale Solve new CAD Sync functionality can save hours and ultimately allow you to get your products to market faster.


Remote Forces:
OnScale Solve now has the ability to apply remote forces.  A Force can be made “Remote” using a new toggle in the Force Load properties panel.  The location of the Remote Force is specified with respect to the global origin. Remote forces provide a way of defining distributed loads on a body (collections of geometric entities like surfaces) where the force is applied at a reference point that can be remotely located from the body and transmitted through the centroid of the body. The motion of the reference point is coupled to the motion of the centroid of the body which is why remote forces are sometimes referred to as distributed coupling loads.  Remote forces can be used to represent loads from components that are not included in the CAD geometry, which reduces the simulation complexity.

Remote forces are available now in OnScale Solve and will be followed soon by torque loads and remote displacement and rotation constraints. Each of these behaves the same way in that they are applied at a (possibly remote) reference point and transmitted to the geometry in a distributed way. 

By default, the geometry that remote loads and constraints are applied to is represented as deformable – that is it has finite stiffness and can undergo stress and strain. The option to represent the geometry as a rigid body will also be available soon in OnScale Solve.

Why is it important to you?

Applying a remote force allows engineers to perform highly accurate simulations without meshing and analyzing extraneous components in large complex assemblies.  For example, you might need to structurally analyze the bending point of a robotic arm but your assembly contains the entire robot along with the end effector.  With Remote Forces, you can suppress the robot body along with the End Effector and position the force and direction of where the End Effector would be in space.  Another example may be a pedal on a bicycle crank arm as seen below.  You can suppress the pedal and position a force where downward pressure would be located.

OnScale Solve now allows users to include the effects of Gravity in the model setup. This can be turned on from under the Mechanical Environment settings, as shown in the below GIF. By default, the value is set to -9.81 m/(s^2) in the Z direction representing the acceleration due to Earth’s gravity.

Why is it important to you?

Often, especially while working with heavy assemblies, it might be important to include the effects of an assemblies’ own weight in the simulations. By simply toggling on the Gravity button, users will now be able to include the effects due to accelerating loads.

Dual State Trees:

With this new release, we have made a change to the access and interaction of the Simulation Modeler Tree in the Modeler area of OnScale Solve.

Why is it important to you? This new change allows for easy access to the Model Tree at every stage of the simulation workflow.

Show Mesh – New Global setting to view the mesh:

The “Show Mesh” setting to view the generated mesh in the Simulator section of the Modeler has moved to the settings gear in the bottom right corner with “Show Lighting”

OnScale CAD Library:

We implemented a new default CAD Library that has the CAD files for all the tutorials listed in our website.

Why is it important to you? This makes it easy for new users, without CAD files, to try and learn OnScale Solve.

Study Validation Warnings and Errors:

With the new release, we have implemented a better warning and error tracking system that provides intuitive feedback to the users on the errors with their model setup.

Why is it important to you?

With Study Validation, you will receive real-time feedback while setting up a study for simulation.

For example, we display a warning sign if a new load you added has 0 magnitude in value. If you don’t add material to a part you’re simulating, you will get a warning message to go back to this critical step.

Deformed mesh:

We have added a feature that allows for the mesh to be deformed while using the Deformation Scale in the Results section.

Why is it important to you?
The visual representation of the deformed mesh provides an intuitive understanding about the nature and extent of different deformations in your model. It also makes for a much cleaner presentation while sharing the results with different collaborators.

Improved Versioning:

Changing/adding new material properties via Scripted Studies will trigger the creation of a new version automatically.

Why is it important to you?
Automatic creation of new versions for model setups with previous simulation results will maintain the versioning integrity in Solve. Even while modifying the code using Scripted Studies, OnScale Solve will recognize the changes made to material properties and auto create a new version if the current version has previous simulation results.

Bug fixes:

  • Fixed a bug where attempting to suppress multiple parts only suppressed a single part
  • Fixed a bug where attempting to view a running simulation would fail with a generic error
