Dear All,

I have set up an analysis in which I run multiple .comm files sequentially. Every file loads a previous .base folder, take results from an EVOL\_NOLI result object (by extracting displacements, stresses and state variables at the last step), DESTROYS the previous result file and run a new analysis (with the same name as the analysis destroyed). In this way, I will end up with multiple independent .base folders and I can extract the results whenever I need it.

The problem is that, although I use DETRUIRE command, the new base seems to contain the old result as well, and thus the size of the .base folders increases exponentially. To solve the problem I have tried to eliminate the dependencies before destroying. This is the code:

> depl = CREA\_CHAMP (

> OPERATION=‘EXTR’,

> NOM\_CHAM = ‘DEPL’ , TYPE\_CHAM = ‘NOEU\_DEPL\_R’,

> RESULTAT = RES ,

> INST = first\_time

> );
> 
> sigm = CREA\_CHAMP (

> OPERATION=‘EXTR’,

> NOM\_CHAM = ‘SIEF\_ELGA’ , TYPE\_CHAM = ‘ELGA\_SIEF\_R’,

> RESULTAT = RES ,

> INST = first\_time

> );
> 
> vari = CREA\_CHAMP (

> OPERATION=‘EXTR’,

> NOM\_CHAM = ‘VARI\_ELGA’ , TYPE\_CHAM = ‘ELGA\_VARI\_R’,

> RESULTAT = RES ,

> INST = first\_time

> );
> 
> RES.clear()

> DETRUIRE(NOM = RES);
> 
> RES=STAT\_NON\_LINE(

> ETAT\_INIT=\_F(

> ```
> SIGM=sigm, 
> 
> ```

> ```
> VARI=vari, 
> 
> ```

> ```
> DEPL=depl, 
> 
> ```

> ),

> …);

> depl.resetDependencies()

> vari.resetDependencies()

> sigm.resetDependencies()

> DETRUIRE(NOM = (depl, vari, sigm));

The problem is only partially solved, since the growth is now continuous but not exponential:

```auto
 du -sh *base
680M 1950.base
722M 1951.base
844M 1952.base
804M 1953.base
828M 1954.base
890M 1955.base
917M 1956.base
941M 1957.base
962M 1958.base
969M 1959.base
978M 1960.base
1019M 1961.base
1,1G 1962.base
1,1G 1963.base
1,1G 1964.base

1,2G 1967.base
1,2G 1968.base
1,2G 1969.base
1,3G 1970.base

```

At the end of each .mess file I see:

where it seems evident that previous EVOL\_NOLI objects, although reduced in size, are still in the .base.

What do you think is happening?

Thank you for any help.
