FAQ

General

What are the advantages of Allsolve over other similar software in the market?

• Allsolve is designed for HPC
• Solve large problems on the cloud
• Parametric sweeps in one-click
• Script interface and API

How secure is my data in the cloud?

We take security seriously! The data on the cloud is very secure. For more information, you may want to read our blog on this topic.

Do I need to buy separate modules for different physics?

No. You get all the physics when you buy Allsolve.

Does setting up the model cost something?

No. Setting up the model doesn’t cost anything to you. Only when you run meshing operation and the simulation, it consumes the core-hours from the assigned quota.

I have lost my second factor authenticator

1. Use another login device
2. Use your backup codes
3. There is unfortunately nothing we can do to restore the account if the above methods fail.

You can ask your organization admin to remove you from the organization and add again.

Model

What is the ‘Fragment all’ operation?

‘Fragment all’ operation creates non-intersecting disjoint geometric entities. E.g., non-intersecting volumes in 3D, surfaces in 2D, and edges in 1D.

Which geometric exchange formats are available for importing the geometric model?

Currently, the following geometric exchange formats are available: STEP and GDS. Also you can import Gmsh .msh files.

Properties

What is a shared expression?

A shared expression is a global expression that is available in all sections of the project. It can be used to parameterize the geometry, material properties, and boundary conditions, and later can be used for parametric sweeps. Read more about expressions.

Can I change the properties of materials from the library?

Yes. All properties of all the materials from the library can be edited for your simulations. However, the edited properties will only be available in that simulation.

Can I create a new material?

Yes. You can create a new material and assign the properties that are relevant for your simulation.

Can I have the material properties dependent on field variables?

Yes. You can create material properties as function of field variables as well as shared expressions.

Can I make the material properties anisotropic?

Yes. You can make some material properties anisotropic by simply checking the provided checkbox. You can then add individual values in the material matrix.

Can the elasticity matrix be written as a function of elastic coefficients?

Yes. In that case, you will have to define elastic coefficients as shared expressions, check the anisotropy box, and edit the individual entries in the matrix.

Simulations

What is DDM

DDM stands for Domain Decomposition Method. This method is used to split the mesh into several pieces and deploy the individual pieces to separate compute nodes for solution thus accelerating the solution speed.

Does Allsolve use iterative or direct solver?

Allsolve by default uses direct solver for the solution. The option of iterative and direct solver are provided for the DDM.

How do I know which nodes and how many do I need?

Ideally, you should start with the smallest node and go for bigger nodes only if you need them due to memory limitations. For multinode simulations a rule of thumb is to have 50-300k DOFs per compute node. So for 1 million DOFs 4-20 would be the sweetspot.

For eigenmode analysis, you may choose a relatively bigger single machine.

Can I postprocess the data after the simulation has finished?

You have to set all the outputs for the simulation before the simulation starts. You can use the internal result visualizer to see the field outputs.

If I log out or my internet is disconnected for some reason, do the simulations still continue to run?

Yes, the simulations will keep running in the cloud until the simulations finishes or the timeout is exceeded.
