Re: Calling a solver from another solver

Nowadays a solver may indeed activate the execution of another solver. For some documentation of different options see the section 13.2 of ElmerSolver Manual (http://www.nic.funet.fi/pub/sci/physics ... Manual.pdf).

Re: Mesh keyword in solver section ?

Hi, The keyword for giving a mesh in solver section is "Mesh". For example, if the mesh files are contained in directory "solverwise_mesh" under the working directory, one may give the command Mesh = "solverwise_mesh". If some solver section doesn't specify a mesh, then...

Re: Relation between “Magnetic Field Strength” and “Magnetic Flux Density” ?

Seeing "Version: 9.0 (Rev: Release, Compiled: 2020-12-13)" I doubt your executable has not been compiled using fresh source files from the devel branch. For example, if the source files are the latest versions from Dec 11, 2020, Elmer is expected to output the revision information as MAIN:...

Re: Flow due to pressure

On the other hand the keyword "Pressure i" defines directly the components of the traction vector s(n) with respect to the basis vectors of the global frame. In this case the normal is automatically directed by Elmer to point outwards from the body containing the fluid. To get the same pro...

Re: Flow due to pressure

Unfortunately the historical choice of some keywords may cause confusion. The keyword "External Pressure" basically defines the surface traction (surface force) s applied to the fluid by the environment in terms of unit normal vector n to the boundary as s(n) = p_ext n. If we neglect visco...

Re: Relation between “Magnetic Field Strength” and “Magnetic Flux Density” ?

There was another bug in the computation of magnetic field strength. This has now been fixed in the devel branch.

Thanks for reporting,

Re: Relation between “Magnetic Field Strength” and “Magnetic Flux Density” ?

Hi, I found a bug in the reluctivity evaluation when the constant "Permeability of Vacuum" was given by the user in the constants section. This has now been fixed in the devel branch. The error wasn't nevertheless just a multiplication by four, so I'm not sure whether this explains your ob...

Re: ElmerToGmshIndex in SaveUtils.F90

Hi,

I believe these issues have now been fixed in the devel branch of the code repository.

Thanks for reporting,

Re: magnetic field of a permanent magnet in 3D

Unfortunately I observed that the postprocessing solver (MagnetoDynamicsCalcFields) has neglected the magnetization vector when the magnetization vector has been given in a material section or only elemental approximations have been calculated. This has now been corrected in the devel branch of the ...

Re: HelmholtzSolve and p-elements

Does the Helmholtz Solver support p-elements? Yes What would be the best way to figure out if a solver supports p-elements? Is trial error a viable way (i.e. will solvers not supporting p-elements produce an error in the logs if the keyword is set?) Unfortunately it is not usually clearly indicated...
