Performing a linear static analysis is as easy as choosing Analysis option from LUMINO. It automatically transfers the finite element data from LUMINO to CAEFEM. Once the analysis is done, results are automatically transfer back to LUMINO for post processing. Of course, you will have complete control in selecting additional options for both the analysis and also for post processing data.
Some of the major features of Linear Static Analysis are:
Calculates natural frequencies and associated mode shapes. Some of the major features are:
Calculates linear buckling load. Some of the major features are:
Calculates steady state response due to external harmonic loads.
Calculates the maximum response due to external loads like earthquakes, wind loads etc.,
Following is a list of major features
Element Name |
Major Features |
Rod |
Two node element. Usually accepts only translational degrees of freedom and hence CAEFEM automatically ignores rotational degrees of freedom. But it considers rotational degree of freedom about its axis, if user specifies nonzero torsional constant. |
Cable |
Same as Rod element except an initial tension can be specified. CAEFEM automatically treats Rod element as a Cable element if nonzero initial tension is specified. |
Bar |
Same as a uniform beam element. |
Beam |
Two node element. |
Tube (Pipe) |
Same as a beam element with an annular cross section. |
Gap |
Two node element. (considers friction) |
Contact |
Surface to surface contact. |
Spring and Damper |
Supports both axial and torsional stiffnesses and dampers. Applicable only for a structural analysis. |
DOF Spring |
User can specify the stiffness values between any two degrees of freedom. Degrees of freedom can be specified in the output coordinate system. Applicable only for a structural analysis. |
Rigid |
Any number of nodes can be connected by a rigid element. Applicable only for a structural analysis. |
Membrane |
Same as a Plane stress element except that it can be located in a three dimensional space. |
Plane Stress |
Supports 3 to 8 nodes. Should be defined in XY plane. |
Plane Strain |
Supports 3 to 8 nodes. Should be defined in XY plane. |
Axisymmetric Ring |
Supports 3 to 8 nodes. Should be defined in XY plane. (Y axis being the axis of revolution) |
Shell |
Supports 3 to 8 nodes. |
Laminated Shell |
Supports 3 to 8 nodes. |
Solid Brick |
Supports 4 to 20 nodes. Degenerated element can be formed by repeating the nodes. |
Solid Tetrahedron |
Supports 4 to 10 nodes. |
Solid Wedge |
Supports 6 to 15 nodes. |
Stiffness Matrix |
User can specify all 36 coefficients of a stiffness matrix. Applicable only for a structural analysis. |
Mass Matrix |
User can specify all 36 coefficient of a mass matrix. Applicable only for a structural analysis. |
Nodal Mass |
User can specify all six components of mass values at a node. Applicable only for structural analysis. |
CAEFEM supports the following types of methods for solution of equations. Depending on the requirement, user can easily select the solution method.
|
Restart of an analysis (available for both structural and heat transfer analyses). CAEFEM recognizes it as a restart of an analysis if user attempts to run the same analysis. Hence no special command is required to continue the analysis from a previous successful time step. |
Aborting an analysis |
CAEFEM allows you to abort the analysis before its completion. It helps you to stop the current analysis for a possible input correction. |
Groups |
CAEFEM now reads all groups information from Lumino. Groups information can be used to control the ASCII file printout, to store different sets of data in CAEFEM database and also to control the results neutral file information. Groups can also be defined / modified in CAEFEM. Choose-Create-Groups to create a new group of entities. Choose Edit-Groups to edit an existing group of entities. |
Print Options |
Displacements, Velocities, Accelerations, Stresses, Strains and Reaction forces. Both nodal and integration point stresses/strains are available. Beam end moments, Plate stress resultants and internal forces at element nodes. Temperature and heat flow rates. Stiffness and mass matrices (both global and elemental matrices) |
Batch Option |
Supports a powerful batch option. It automatically runs all the specified analyses and prepares post processing files. |
DLL Interface |
Supports Dynamic Link Library interface. It allows the customization of CAEFEM. |
Supported by over 1000 internal verification and NAFEMS bench mark problems. This set includes problems with known analytical solutions, problems from the finite element analysis literature, large problems etc., A large set of output values are automatically compared with the reference solution to maintain the high quality of the software.
