This ppt gives an introduction to Hypermesh and its basic functions.

1. STARTING WITH HYPERMESH
MADE BY:

SUPPORTED BY:

AIDED ENGINEERING

2. • THE VERY FIRST THING THAT POPS-UP IS THE USER PROFILE
DIALOGUE BOX.
• IT SPECIFIES THE KIND OF MODEL OR PROJECT YOU WOULD
BE WORKING WITH.
• FOR EXAMPLE: OPTISTRUCT PROFILE IS FOR A MODEL
INVOLVING STATIC ANALYSIS WHILE LS-DYNA PROFILE IS FOR
MODELS INVOLVING DYNAMIC ANALYSIS.
FIRST THING TO OBSERVE

3. • NODE IS A POINT IN HYPERMESH
• CLICK ON NODES
• SPECIFY COORDINATES (X,Y,Z) AND CLICK ON CREATE.
• A NODE WILL APPEAR. (IF NOT, PRESS F TO MAKE VIEW FIT TO SCREEN)
• NOTE AFTER SPECIFYING COORDINATES ONE CAN ALSO PRESS THE SCROLL WHEEL ON YOUR MOUSE TO
CREATE THE NODE.
CREATING GEOMETRIES - NODES

4. CREATING A CUBE – WITH LINES
• LETS SAY THE LENGTH OF SIDE OF CUBE IS 100.
• FIRSTLY, YOU WILL NEED TO CREATE NODES ON ALL THE COORDINATES OF THE CUBE USING
THE STEPS LEARNT IN PREVIOUS SLIDE (AS SHOWN).
• NOW, CLICK ON LINES OPTION JUST NEAR NODES OPTION. UNDER IT SELECT LINEAR NODES
OPTION (SELECTED IN THE PICTURE).
• NOW YOU WILL SEE NODE LIST OPTION ACTIVATED. NOW CLICK ON TWO NODES TO CREATE
A LINE BETWEEN THEM. AFTER SELECTING TWO NODES CLICK ON CREATE OR CLICK USING
MOUSE WHEEL.

5. • FIRST CREATE A NODE AND GO TO TOOLS OPTION
• UNDER IT FURTHER GO TO TRANSLATE OPTION.
• SELECT THE NODE CREATED AND CHOOSE GLOBAL SYSTEM AS SHOWN.
• SELECT THE AXIS, PARALLEL TO WHICH THE NODE WILL BE TRANSLATED.
• PROVIDE THE MAGNITUDE BY WHICH IT NEEDS TO BE TRANSLATED.
• ALSO YOU MAY CREATE 4 NODES ON A PLANE AND TRANSLATE THEM SIMULTANEOUSLY BY
SELECTING ALL THE 4 NODES TOGETHER AND FOLLOWING THE SAME PROCEDURE.
CREATING A CUBE – WITH LINES (USING TRANSLATE COMMAND)

6. • TO CREATE SURFACES, CLICK ON SURFACE OPTION NEXT TO LINES OPTION.
• UNDER IT, SELECT SPLINE/FILLER OPTION (SELECTED IN THE PICTURE).
• UNCHECK THE AUTO CREATE AND KEEP TANGENCY OPTIONS AS SHOWN (IF THEY ARE
CHECKED).
• NOW, WE NEED TO SELECT 4 LINES TO CREATE A SURFACE (IN OUR CASE).
• USUALLY WE NEED TO SPECIFY A CLOSED LOOP OF LINES TO CREATE A SURFACE.
• NOTE: EVEN AFTER CLICKING ON CREATE, IF THE SURFACE DOES NOT APPEAR, CLICK ON
SHADED GEOMETRY AND SURFACE EDGES. (SHOWN IN THE PICTURE)

Shaded Geometry &
Surface Edges

7. WHY WE LEARN THESE MODELLING STEPS?
• USUALLY HYPERMESH IS NOT USED TO CREATE MODELS OF COMPONENTS BUT SOMETIMES WHEN
WE IMPORT HUGE MODELS TO ANALYSE THEM, THERE MAY BE SOME ERRORS WHICH CAN BE
MODIFIED USING SOME BASIC TOOLS IN HYPERMESH.
• ALSO, AFTER ANALYSIS, ANY JOINT/COMPONENT WHICH FAILS IN THE TEST CAN BE MODIFIED
EASILY USING SOME BASIC FUNCTIONS IN HYPERMESH.
• THEREFORE, THESE STEPS CAN HELP US TO MAKE CHANGES IN THE MODELS IMPORTED AND
IMPROVE THE DESIGN.
