General

Moment loads can be applied to faces (solids and shell 2D faces) even for elements without rotational DOF.

Direction of displacement constraints can be a function of position to allow cylindrical and other coordinate systems.

Opens .unv mesh files

New units - Gal (cm/s^2) and mm^2/N (1/MPa)

Stress linearization - stress classification line doesn’t have to pass through nodes and settings are saved with the model

Pressure XYZ (traction) can be a function of position.

Load cases replaced by configurations:

Load cases Configurations

Only 7 types of load All loads and constraints

Only static analysis type All analysis types

Only internal solver Both the internal and CCX solvers

A load can only be in one load case A load can be in multiple configurations

Solved simultaneously Solved one at a time

Table can include multiple load cases Table only shows the active configuration’s data

Factor of safety with Von Mises failure criterion for shell elements

Multiple gravity loads can coexist.

Multiple sets of node temperatures are allowed and can be suppressed independently.

Labs feature: Direct force per unit length and shear force per unit length outputs for shells

Write solution to .liml file includes the modeler model

Can read *BEAM GENERAL SECTION from CalculiX .inp files

Fixed bugs 9 and 10 about hydrostatic and position-dependent pressure on thick shell faces

CalculiX solver

Includes 64 bit CCX 2.11

Pressure XYZ (traction) for linear analysis

Pressure can be a function of position for linear analysis

Multiple time dependent force loads on the same node

Convection (*FILM)

Node temperature for thermal stress

Pyramid element faces for pressure, convection, and surfaces

Time dependent formulas in loads are evaluated at automatically chosen time points.

Meshing tools

Gmsh mesher (not included) for STEP files

Change shape option quad8 → 2 x tri6

Refine x2 refines line elements independently of their adjacent elements if they’re not fully connected to them.

Merge nearby nodes with a zero tolerance merges exactly coincident nodes.

UI

Local refinement spheres are shown graphically

Contour plot of values can have different colors for above and below the range

Edge detecting selection is more reasonable with curved quadratic element faces

has the MT-version of SPOOLES  been compiled?

I've 1cpu for spooles again, and I wrote all possible enviroment variables

Sergio

There is no MT-version on the final release. I have recovered from the beta 3 and selected in the Options/Calculix window. Maybe there are some mistakes present so the author has decided not to include.

By the way, why exist an option to select an CCX input file editor as well? I don't remember if there is an option to edit using an exernal editor.

Victor

Yea, I removed the MT version because of the buckling error that Andrea found.

The .inp file editor is for viewing the generated file when you press the ".inp file" button on the solver panel. It won't automatically use any edits you make but you could save and solve it separately though.

Andrea

I use Scite as a editor. This editor prepared by J. Baylor has the integration with CCX and CGX. So you can launch the pre-solver-post directly from the text editor

Hi. I have been too spoiled by using high end systems for to long.

How do i proceed to convert displacement constraints to a function of position to allow cylindrical and other coordinate systems. This would be very helpful to have a tutorial on.

Also is it possible to use the same functionality to define element local coordinate systems in order to define anisotropic materials to materials?

Victor

You can enter a formula in each of the boxes for the direction of the displacement. For example, the X, Y, Z components being x, y, 0 respectively defines a radial displacement direction as in the attachment.

It's not yet possible to use formulas for the element coordinate systems but I hope to add this soon.
