Space

Space Spacename

Each object is given a unique name Spacename.

.path = Design.stl

The path is the name of the file.

.material = Steel

User-defined material name. This will not be used any further in the optimisation process.

.E-Modul = 210000.000000

Young's Modulus according to the unit scheme used (here MPa).

.Poisson = 0.33

Poisson 's ratio.

.density = 7.9e-9

Density of the material.

Cells

Mask Maskname

Each object is given a unique name Maskname.

.path = Non_Design_Region_1.stl

The path is the name of the file.

Mask.Non_Design_Region_3.nonDesign

Defines the mask as a Non-Design Region

Mask.Non_Design_Region_3.useCentreOfTheSurface

Mask.Non_Design_Region_3.useOnlySurface

The mask represents a surface.

Mask.Non_Design_Region_3.preserve

The mask cannot be removed during the optimisation and will keep a connection to the

Local Coordinate Systems

CoordinateSystem Coordinate_System_1

Each coordinate system is given a unique name Coordinate_System_1

.euler1z =0.000000

.euler2x = 2.417309

.euler3z = 4.712389

.x = -0.071360

.y = -0.022816

.z = 0.02185

The coordinate system is located/orientated with coordinate values and Euler angles regarding the global coordinate system.

Load Force_-_Moment_1

A force is marked with the word "Load" and additionally gets a name. 

Moment Force_-_Moment_2

A moment is marked with the word "Moment" and additionally gets a name.

Acceleration Apply_gravity_1

.space =

An acceleration is marked with the word "Acceleration" and additionally gets a name.

The acceleration is always applied to the whole Design spaceSpace.

Pressure Pressure_1

A pressure load is marked with the word "Pressure" and additionally gets a name.

Displacement Constraint_1

A fixation is marked with the word "Displacement" and additionally gets a name (dis1).

For fixations, the degree of freedom (x, y, z) is subsequently defined by a prescribed displacement of 0.

.mask = Maskname

The mask affected by the boundary condition (Maskname) is selected

.x =

Boundary condition in x-direction

.y =

Boundary condition in y-direction.

.z =

Boundary condition in z-direction.

solver=

Extern

CG

Connection to the solver.

External CudaSolver.

CG Uses an integrated conjugated gradient solver.

solverIP=localhost

IP of the external solver, localhost for the same workstation. IP for cloud, for what the matrix is built locally and sent to the calculation unit. Large amounts of data can be moved with a corresponding amount of time.

solverPort=1234

Port which is used to access the CudaSolver. This can be selected arbitrarily, according to the specified value when starting the solver.

eigenThreads=2

Number of CPU threads that can be used to build the matrix. At least two cores should always remain free. We recommend to use 2-6 threads.

complexity=14.000000

Defines how complex the design is getting. More information here.

solverUsedGpuMax=n

Maximum number of GPUs used by the optimisation (support GPUs: Nvidia Quadro Graphics Cards supported by CUDA Driver)

detail=auto

Detail refers to the edge length of the FEM elements and can either be calculated automatically depending on the "complexityComplexity" or set manually. In the case of a defective stl ST-file, the detail should be set manually, since the calculation of the volume has an error and the automatic estimation cannot take place. A reduction of the detail by half results in an 8-times change of the calculation time.
