Units Data

This group of data refers to all the general units required to identify general and boundary conditions data of the problem.

Tdyn Units Data window can be started from Data > Units Data .

Options available in IN/OUT page

Output Length Units : Length units used in the output data (written in the results file).

Output Mass Units : Mass units used in the output data (written in the results file).

Output Time Units : Time units used in the output data (written in the results file).

Output Temperature Units : Temperature units used in the output data (written in the results file).

Output RamSolid Units : Units used in the output data of structural analyses (written in the results file).

Internal Length Units : Length units used in the internal calculations. This value should be changed if the dimensions of the geometry are so small (large) that the precision of the calculations may be affected.

Internal Mass Units : Mass units used in the internal calculations.

Internal Time Units : Time units used in the internal calculations.

Internal Temperature Units : Temperature units used in the internal calculations.

Options available in GEOMETRY page

Geometry Units : Length units used in the geometrical definition of the problem. Geometry and mesh of the problem will be understood to be defined in this units.

Options available in GENERAL page

Boundary Length Units : Length units used in the definition of the boundary conditions of the problem.

Boundary Mass Units : Mass units used in the definition of the boundary conditions of the problem.

Boundary Time Units : Time units used in the definition of the boundary conditions of the problem.

Boundary Velocity Units : Velocity units used in the definition of the boundary conditions of the problem. They are also used for definition of the initial data of the problem (see section for further information).

Boundary Pressure Units : Pressure units used in the definition of the boundary conditions of the problem. To make easy the data insertion in the preprocessing, used Pressure is divided by fluid density. They are also used for definition of the initial data of the problem (see section for further information).

Boundary Kenr Units : Eddy kinetic energy (k ) units used in the definition of the boundary conditions of the problem. They are also used for definition of the initial data of the problem (see section for further information).

Boundary Elen Units : Turbulence length scale (L) units used in the definition of the boundary conditions of the problem. They are also used for definition of the initial data of the problem (see section for further information).

Boundary Temperature Units : Temperature units used in the definition of the boundary conditions of the problem.

Boundary Angle Units : Angle units used in the definition of the boundaries of the problem.
