Advanced Mesh Control Tools - Now available in version 12.0

Meshing is an important part in achieving accurate solutions across our 2D, axisymmetric, and 3D solvers. Whether you are using the Boundary Element (FEM) or the Finite Element (FEM) solver, understanding the element mesh is essential for all users.

Version 12.0 of our software introduces advanced mesh settings that allow users to have a greater control over mesh generation for their models.

Achieve faster and more precise meshing with:

  • Global Mesh Settings – Control size, quality, and refinement for 1D, 2D, and 3D meshes.
  • Mesh Overrides – Fine-tune element size, shape, and curvature in key areas.
  • Mesh Weighting – Prioritize regions for higher accuracy without extra solving time.

Significance of resultant magnitude of the electric field in COULOMB for phasor mode of operation.

Dr. K.M. Prasad - Senior Application Engineer

Software: Coulomb™

In COULOMB, when the Operation Mode is set to Phasor (Single Frequency). The electric field components will be phasors viz:

  • Εx = a + jb
  • Εy = c + jd
  • Εz = e + jf

Εmagnitude = g + jh = √ [(Εx)(Εx) + (Εy)(Εy) + (Εz)(Εz)]

Real Part {Εmagnitude} = g
Imaginary Part {Εmagnitude} = h
Magnitude {Εmagnitude} = sqrt [g*g + h*h]

All the above quantities (Εx, Εy, Εz, Εmagnitude ) are the rms (root mean square) values.

Let the unit vector of the normal to a surface/plane at the point of observation be {Nx, Ny, Nz}

The normal component of electric field is given by,

Εnormal = Nx*Εx + Ny*Εy + Nz*Εz = {(Nx*a+Ny*c+Nz*e) + j(Nx*b+Ny*d+Nz*f)} = m + jn

Magnitude {Εnormal} = √ [m*m + n*n]

Theoretically, on a conductor surface Εmagnitude = Εnormal. However, an insignificant difference (numerical noise) may exist between Εmagnitude and Εnormal. Therefore, Εmagnitude on a conductor surface is also the same as Εnormal.

In the model space at an observation point on an observation plane/surface, Εmagnitude is not equal to Εnormal. Therefore, in the model space at an observation point on an observation plane/surface, Εmagnitude is the rms value of the resultant magnitude of the electric field.
