Import cdb I File

In version 5.0 of CAE Fidesys, it was possible to import a cdb file. The cdb format is an archive format supported by the Ansys software package.

These files contain the following information about the model: finite element mesh, material, boundary conditions, analysis type, calculation parameters.

Below is information about the capabilities of the cdb envelope in the CAE Fidesis software package.

Table 1 - Conversion of types of analysis
Analysis (Fidesys)	Analisis (Ansys)	Result
Static	Antype,Static	Static
Mode Frequency Analisis	Antype,Modal	Analysis of frequencies, waveforms
Buckling	Antype,Buck	Calculation for buckling

Table 2 - Conversion of finite element types
Element (Fidesys)	Element (Ansys)	Result
Solid	solid185	Solid (1 order)
Solid	solid186, solid187	Solid (2 order)
Shell	shell181,shell281	Shell (1 or 2 order)
Beam	beam188,beam189	Beam (1 or 2 order)
Linear spring	combin14	Spring (type - linear)
Combination spring	combin40	Spring (type - combination)
Discrete mass element	mass21	LumpMass
Combin with coincident nodes	combin14	Boundary Condition "coupling with stiffness"

Table 3 - Conversion of boundary conditions
BC	Name of the APDL team responsible for this BC	Result
Displacement	D;DK;DL;DA	Displacement (entities - nodes))
Node Forse, Moment	F	Forse (entities - nodes)
Binding degrees of freedom	COUPLING	Coupling Constraint (variables)
Bonded region	CERIG	Coupling Constraint (distance between entities)

Table 4 - conversion of the physical properties of the material
Properties	Properties (Ansys)	Result
Linear elastic isotropic material (Young's modulus, Poisson's ratio)	Linear Isotropic Material Properties (EX,PRXY)	Isotropic material (Young's modulus, Poisson's ratio)
Mass density	Density	Density
Thermal expansion coefficient	Isotropic thermal Secant Coefficient	Thermal expansion coefficient

In Fidesys 5.0, it is now possible to convert the surface load from the Ansys package. The result of this conversion will be the "Distributed force" field located in the "Loads" tab.

The correspondence of the Ansys and CAE Fidesys elements is clearly shown in the picture below

Important: when exporting a model from Fidesys, Cyrillic characters should not be allowed, as this may lead to an import error in Ansys.
