List of New Features

Modeling

• By expanding the selection from the selected object, collectively select objects according to conditions. ->[Advanced Selection]
• Wire/Sheet/Solid body converting supports conversion of multiple bodies.

Stress Analysis

• The domain decomposition method has been improved for faster calculation in static analysis.

Acoustic Analysis

• The option [Use the specific acoustic impedance calculated from material] is added in the acousitic impedance boundary condition.
  Selectable in harmonic analysis Acoustic Tab.

Piezoelectric Analysis

• The [Impedance Graph (Resonant Analysis)] tab is added to the result table. -> Resonant and antiresonant frequencies are output. Displayable Results for Each Analysis
  At the acquired resonant frequency, the impedance is minimized on the impedance graph.
• The calculation method for [Spread between resonant and antiresonant frequencies] in the result table is updated for higher accuracy.

Fluid Analysis

• Cell-centered solver Is available in the fluid/fluid-thermal analysis.
  Fluid can be analyzed with polyhedral meshes as well.
  
• The outer boundary condition is automatically set based on the specified flow type. ->[ Fluid Analysis Tab]
  
• A fluid domain is automatically created based on the specified flow type.
  If internal flow is selected, tutorial: Fluid Analysis_2 (Bernoulli, Diffusion Analysis: Automatic Internal Fluid Creation).
  If external flow is selected, tutorial: Fluid-Thermal Analysis (Bernoulli_Watt, Automatic External Fluid Creation) and Example 3: Cooling of IC by Forced Convection.

Thermal Analysis

• A fluid domain can be automatically created in the closed domain surrounded by solids. -> Example 30: Cooling of IC inside the Case
  
• With the hemicube method additionally implemented, discrete GPUs can accelerate the search of radiation surfaces in surface-to-surface radiation. -> High-Level Setting Tab

 

Solvers

• Restarting is improved for easier use. -> [Calculation Finished] dialog
• Intermediate results can be easily deleted in order to reduce the file size. -> [Calculation Finished] dialog

 

Show results

• The field to be displayed can be selected or added. -> [Select, edit, or add fields]
• User-defined fields have become easier to use. -> [Edit user-defined field] and [User-Defined Sample].
